UT-day observing yields the most accurate combination and comparison of results from other techniques. This will also be the operation mode of VGOS observing. ===================================================================== Number of 24-hr sessions: 15 Participating stations: Badary, Fortaleza, HartRAO (15-m), Hobart (12-m and 26-m), Katherine, Kokee, Matera, Ny Alesund, Onsala, Tsukuba, Warkworth, Westford, Wettzell, Yarragadee, Yebes, Zelenchukskaya Average number of scans per day: 1,622 Average number of observations per day: 20,141 Total number of scans in campaign: 24,336 Total number of campaign observations: 302,115 ===================================================================== Schedules The sources for the schedules are based on the best 100 sources. From those, sources were removed iteratively that only contributed 5 observations and less. Further, four sources that showed more than 20% of non-detections in the R1 and R4 sessions over the last six months prior to CONT14 have been removed as well. In a final step ICRF2 special handling sources were added to the list, resulting in 73 sources used for creating the schedules. The sources for the schedules are based on the best 155 sources (120 from the geodetic.good catalog and 35 special handling sources). From the 155 sources, sources were removed in an iterative process that contributed five or less observations. The first iteration resulted in 81 remaining sources and the last iteration resulted in 77 remaining sources. Further, four sources that showed more than 20% of non-detections in the R1 and R4 sessions over the last six months prior to CONT14 were removed as well. This resulted in 73 sources for the CONT14 campaign, 50 geodetic.good sources and 23 special handling sources. SNR Targets: Minimum SNR for all baselines (except with Hobart-26m): X-band (margin 0): 20 S-band (margin 0): 15 Minimum SNR for baselines with Hobart-26m: X-band (margin 0): 18 S-band (margin 0): 13 ===================================================================== Special Instructions Refer to the schedule summary at the end of the file for the overall schedule of sessions. One, two, three, or four session days will be recorded onto one disk module. Several session days are grouped together for sharing disks creating the following recording groups for all stations. PLEASE DO NOT CHANGE RECORDING GROUPS, PLEASE FOLLOW AS LISTED. Recording groups for Bd, Ft, Hb, Ho, Ht, Ke, Kk, Ny, Ts, Wf, Ww, Wz, Yg, Ys, and Zc: C1401 ==> ---+ C1402,C1403 ==> | C1404,C1405,C1406,C1407 ==> +---> Ship or e-transfer C1408,C1409,C1410 ==> +---> to Bonn Correlator C1411,C1412,C1413,C1414 ==> | C1415 ==> ---+ Recording groups for Ma and On: C1401 ==> ---+ C1402,C1403 ==> | C1404,C1405 ==> | C1406,C1407 ==> +---> Ship all modules to C1408,C1409,C1410 ==> +---> Bonn Correlator C1411,C1412 ==> | C1413,C1414 ==> | C1415 ==> ---+ All CONT14 sessions will be correlated at the Bonn Correlator. This includes also the R4-equivalents. The data transport to the correlator will be done either by physical shipment of modules or by electronic transfer of data (e-transfer). The following stations will ship their recording modules to the Bonn Correlator: Bd, Kk, Ma, On, Wf, Wz, Ys, and Zc. The station Ft will ship their modules to the Washington Correlator (WACO). WACO will then e-transfer the Ft data to the Bonn Correlator. The following stations will e-transfer their data to the Bonn Correlator: Hb, Ho, Ht, Ke, Ny, Ts, Ww, and Yg. CABLE CAL CHECK: A cable check should be performed before the start of the first session and after the end of the last session. Stations should NOT do any cable cal checks (or anything else that might interrupt the 5 MHz to the antenna unit) between sessions. SYSTEM CHECKS: With the exception of C1401 and C1415, all CONT14 sessions have a one-hour slot for each station to perform system and pointing checks. The one-hour slots for all stations are staggered over the 24-hour period of the session. Stations should check the system and pointing during the one-hour slot preferably during the first 30 min of the slot (to allow for corrective measures in the subsequent 30 min if necessary). The station is scheduled in tag-along mode during the one-hour slot allowing the station to leave and re-enter the session at any given moment of the slot. The stations should rejoin the current schedule as soon as practical. The stations observing the various Intensive sessions have a 90-min break from the CONT14 schedule followed by a 30-min period for system and pointing checks, resulting in a two-hour slot (readily identifiable in the table below by the 1/4 of an hour start and stop times). The "Intensive stations" were also scheduled in tag-along mode during the two-hour slot. The system and pointing checks, however, should be performed after the Intensive observation. The slots are as follows (for C1402 through C1414); the first day of CONT14 (C1401) and the last day (C1415) have no station check times.

Before rejoining please consider the slewing time from the antenna's current position to the next scan, including which cable wrap the antenna should be on. You may need to pick a slightly later scan in order to have enough slewing time and reach the correct cable wrap. A suggested technique for breaking away from the schedule is to use the "halt" command to stop the schedule to begin the system checks. Once checks are complete and the scan to rejoin the schedule has been determined, a suggested way to rejoin is to use the following command: schedule=session,#line where "session" is the name of the .snp schedule file and "line" is the line number for the scan shown in the schedule listing. MODULE SHIPPING: The modules can be sent as soon as no further recording is planned on them. This can be at the end of a single session (C1401, C1415) or at the end of a set of sessions (recording group). Stations should label the modules to indicate which session(s) the modules contain. The R-type sessions will be processed within the nominal 15 day time delay for the rapid sessions. These sessions require that the modules be shipped to the correlator expeditiously. Rapid sessions are C1401, C1403, C1407, C1410, and C1414. E-TRANSFER: The data of the R-type sessions need to be transferred as soon as possible and all rapid sessions (C1401, C1403, C1407, C1410, and C1414) are to be transferred before any of the other sessions. The Bonn Correlator has a limited bandwidth for e-transfers (1 Gbps). Hence, e-transfer rates are limited for each station to around 100 Mbps. The transfer of a single session will thus take up to three full days per station. The Bonn Correlator might be able to increase bandwidth for CONT14 for a limited time. The e-transfer stations should consult with the Bonn Correlator on organizing the e-transfers. MIDOB: Each station should verify that their MIDOB procedure completes in 20 seconds or less. The minimum scan length is 20 seconds. MARK 5B OPERATIONS: Stations using Mark 5B recorders should be aware that they should not automatically re-sync the 5B if they receive the error message: ?ERROR sc -24 setcl: Mark 5B syncerr_gt_3, use fmset 's' option to fix. This error message is poorly worded. Newer FS versions have the message ("using" misspelled): ?ERROR sc -24 setcl: Mark 5B syncerr_gt_3, CONSIDER uisng fmset 's' option to fix. You should not use fmset to re-sync the Mark 5B unless fmout-gps is greater than +/- 30 milliseconds. If you do a re-sync, please be sure the time is correct as well. In other cases, you should not reset the Mark 5B time unless it is off by more than +/- 5 seconds (as shown by setcl in units of 0.01 seconds). For the station using a DBBC (in particular AuScope stations), if the fmout-gps starts to change continuously, it may be worthwhile to reset the DBBC (and re-sync and set the time in the 5B with fmset), if that will stop the continuous changing. B2A PROBLEM: Please be aware that for some Mark 5 recorders it is not possible to record a module in bank A if it has already been recorded on in bank B. There should not normally be a need to move a module from one bank to another. However, if it does, please be aware of this restriction. KEY SWITCH ISSUE: We would like to remind all stations to not touch the Mark 5 while it is recording. If you turn a key switch while recording, even for the inactive bank, you will probably corrupt the data on the active disk pack. Additionally, if the key for the inactive bank is turned to locked, the Mark 5 will not respond to some commands from the FS for 20 seconds or more. Please turn the key to "unlocked" only when not recording. Please turn the key to "locked" only when the Mark 5 is not recording and the FS will be idle for at least 20 seconds. If you have any questions about this , please contact Ed, (Ed.Himwich@nasa.gov). LOG FILES: Log files should be ftp'd to an IVS Data Center every day, following the end of each session. This will ensure the logs are available for the correlator to set up for pre-passing and for processing the rapid sessions. It will also let the status of each station be checked. Automatic scripts process the logs each night, the summary files and plots are posted on the session web page, and the session performance matrix is updated. STARTING SCHEDULES: For the first schedule you will need to make sure that you start it early enough to reach the first source. Please check to make sure you go to the right cable wrap for this scan. If your antenna interface does not support the "cable wrap" parameter for the "source=..." you may need to force the antenna to the right wrap manually. Of course changing the wrap will require additional time if it is needed. The cable wrap needed can be found in the DRUDG listing (for example the one from option 5) or from the "source=..." command in the .snp file. Starting with the second schedule we have allowed enough time to slew to the new source from the last source in previous schedule if the schedule is started by 0000 UT. The cable wrap should be handled correctly without taking special action if this rule is followed. In order to get as much data, and with as few gaps, as possible, we have allowed a minimum of only three minutes for changes between schedules. In other words, at a schedule transition the old schedule will end recording by 23:57:00 UT and the operator needs to start the new schedule before 00:00:00 UT. This is a short time, but we think it should be sufficient. For stations with Mark 5 recorders we think that at most two operator actions should be needed for a schedule transition. The first action is that between some schedules it may be necessary to change the recording bank with a "mk5=bank_set=inc;" command and then wait up to 20 seconds for the recorder to settle for the "Selected" LED to come on. The second is that every schedule transition will require the new schedule to be started with a "schedule=..." command. The "bank_set" command should require less than 30 seconds for the operator to enter and 20 seconds or so for the Mark5 to complete since the module can already be inserted. The "schedule=..." command should require 30 seconds or less to enter. This still leaves an additional minute and a half or so in case an old module must be removed and a new one inserted and selected and/or there are minor problems. In case of a more serious problem, please rejoin the schedule as soon as possible. Since we are not expecting many problems, we didn't want to allow a lot of extra time to handle them, but we recognize that they may happen. Once the schedule has started, you will need to quickly enter a "mk5relink" to continue the schedule after the "halt" in "ready_disk". We aren't as familiar with K5 operations, but the personnel at Tsukuba have in the past felt that three minutes is sufficient time. Assuming that there is no need to insert a module, it is possible to automate the transition for Mark 5 stations. The cable wrap information is carried forward between consecutive schedules to make this possible. There are many possible ways to automate this. One is to place a procedure, perhaps called "change", in the "station" procedure library with contents similar to: "uncomment next two lines if a bank change is needed "mk5=bank_set=inc;" "!+30s schedule=c14nnxx,#1 where "nn" is the schedule number and "xx" is the station's two letter code. Before the schedule change time, the operator would enter a time schedule command such as: change@2014.ddd.23:58:00 where "ddd" is the day number. The contents of "change" would need to be modified for each transition, changing the schedule name and possible commenting/uncommenting the "mk5=..." and "!+30s" commands as appropriate. You will also need to comment out the "halt" in your "ready_disk" procedure. This approach has *NOT* been tested, but we expect it to work. If you want to use this approach, it can easily be tested before use and/or should be monitored the first time it is used. Other schemes are possible as well. READY, START, and STOP messages: Stations are requested to slightly modify their normal procedures for sending READY, START, and STOP messages. Please send the normal READY and START messages for the first experiment and the normal STOP message after the last experiment. Due to the quick transitions between schedules and the separate system check time, the procedure for the other messages should be modified to make them reasonable. A suggested scheme would be to send the STOP message as soon as convenient after the start of the next schedule. The START message for the new schedule can be sent as soon as convenient after that. The READY message can be sent after the system checks later during that schedule, summarizing the results for those checks and any other status information. If you normally use "msg" to send your READY, START, and STOP messages, you probably still can. However, for the second and following schedules the following changes are recommended: (1) For the STOP message, please be sure the correct (previous) session name is shown and enter disk inventory only for CONT14 modules. Any problems should be summarized in the "comments" text box. Please be sure to include information about any problems with disk modules requiring use of a spare. (As a reminder, please be sure to send a timely message about any disk module problem to ivscc@ivscc.gsfc.nasa.gov when the incident happens. The sooner the Coordinating Center is informed of a problem, the better the chance that a useful response will be possible.) (2) After sending the previous schedule's end message, select the START message form manually and enter the required information. Please verify that the name of the session is correct. If you have the name and time for the first source that was observed, please enter it. Otherwise, you can use 0000 as the time and "source" as the name of the source. (3) After performing the system checks, please select the READY message form manually and enter the information as appropriate including the session name. Please be sure to de-select the "auto-start" check-box on the form. You can turn it off persistently using the "auto-start" check box on the "Setup" menu. (If you do that, please be sure to re-enable it after CONT14 is finished.) If "auto-start" is accidentally selected when a READY message is sent, it may be possible to cancel the message on the START form before an erroneous message is sent, but if not, please don't worry about it. (As a reminder, *** please be sure to NOT do a cable check during the system checks. ***) MARK5 MODULE PREPARATION: Please prepare all modules you will use for CONT14, including spares, before the session begins. It is strongly recommended that all modules be conditioned after shipping and before recording. Whether a module has been locally conditioned or not, it is *necessary* to perform the so-called "FS Checks" procedure for *every* module and to perform it using the Mark 5 it will be recorded in. This procedure has recently (April 17) been re-distributed to the CONT14 stations that use Mark5s. Please note that you must use the large directory size when checking the modules for. This means to use the command reset=erase with no additional parameters. If you do not have a copy of the message or have any questions. please contact Ed (Ed.Himwich@nasa.gov). Please monitor the first "scan_check" after a change of module, particularly at schedule transition, to make sure the new module is working. If not, please change to a spare module and rejoin the schedule as soon as possible. Please set the bad module aside, inform the Coordinating Center (ivscc@ivscc.gsfc.nasa.gov) and only try to re-use it if you have otherwise run out of media towards the end of CONT14. ===================================================================== Table 1: CONT14 Observing Plan Summary Day Code Start End Correlator Rapid --- ----- ---------- ---------- ---------- ----- Mon system check cable check Tue C1401 126-000000 126-235700 Bonn *R1* Wed C1402 127-000000 127-235700 Bonn (this session includes a system check) Thu C1403 128-000000 128-235700 Bonn *R4* (this session includes a system check) Fri C1404 129-000000 129-235700 Bonn (this session includes a system check) Sat C1405 130-000000 130-235700 Bonn (this session includes a system check) Sun C1406 131-000000 131-235700 Bonn (this session includes a system check) Mon C1407 132-000000 132-235700 Bonn *R1* (this session includes a system check) Tue C1408 133-000000 133-235700 Bonn (this session includes a system check) Wed C1409 134-000000 134-235700 Bonn (this session includes a system check) Thu C1410 135-000000 135-235700 Bonn *R4* (this session includes a system check) Fri C1411 136-000000 136-235700 Bonn (this session includes a system check) Sat C1412 137-000000 137-235700 Bonn (this session includes a system check) Sun C1413 138-000000 138-235700 Bonn (this session includes a system check) Mon C1414 139-000000 139-235700 Bonn *R1* (this session includes a system check) Tue C1415 140-000000 140-235959 Bonn Wed cable check Notes for stations: - Do NOT do any cable checks other than the two checks shown. - Each schedule will end no later than the listed "End" time. - When schedule days change, enough time has been allowed to slew from the last source of the old schedule to the first source of the new schedule assuming the new schedule is started by 0000 UT. The actual first observation can be up to a few minutes after the nominal start. - Shipping stations must send modules for the "Rapid" sessions express to the correlator, as usual. e-transfer stations need to transfer the data of all "Rapid" sessions first; non-"Rapid" sessions shall be e-transferred after all "Rapid" sessions are completed. The correlator is Bonn for all sessions. - e-transfer stations need to keep all modules onto which CONT14 data were recorded until the Bonn Correlator gives the go-ahead to re-use these modules for other sessions. - Stations should label the disk modules with DRUDG printed labels to show which CONT14 session days are recorded on them. - Stations should confirm all initiated shipments to the correlators. - For the non-Intensive stations, there are one-hour slots for system checks (see Table in SYSYEM CHECKS). The system checks should preferably be performed in the first 30 min of the one-hour slot to allow for corrective measures in the subsequent 30 min if necessary. The re-entry can occur at any time during the one-hour slots, as the stations are added in tag-long mode during that period. Please consider the cable wrap when re-entering. - The observation of the Int1, Int2, Ru-U Intensives will continue during CONT14. There will be no Int3 Intensive. The slots for Intensive observing and system checks are two hours and aligned with the Int1 Int2, and Ru-U Intensive observing periods. The stations Bd, Kk, Ts, Wz, and Zc will leave the CONT14 schedule at the beginning of their two-hour slots and re-join it after the Intensive and their system checks as soon as possible. The system checks should be performed in the last 30 min of the two-hour slot. The re-entry can occur at any time during the two-hour slots, as the stations are added in tag-long mode during that period. Please consider the cable wrap when re-entering. - If necessary, it should be possible to automate the change in schedules. If you want to do this and want advice, see above or please contact Ed (Ed.Himwich@nasa.gov). Notes for the correlator (BONN): - A disk module may contain data of one, two, three, or four observation days. The disk modules have labels according to the sessions being recorded. - The Int1, Int2, and Ru-U Intensive sessions will be observed during CONT14. There are no Int3 Intensive sessions scheduled. The correlation of the Int1, Int2, and Ru-U sessions will be done at the Washington, Tsukuba, and IAA correlators; the shipment of the data for the Intensive sessions has precedence over CONT14. - Five of the 15 CONT14 days are considered rapid turn-around sessions. These R1 and R4 equivalents are to be correlated first. The equivalents are: C1401 = R1, C1403 = R4, C1407 = R1, C1410 = R4, C1414 = R1. - The accumulation period (AP) should be set to 1 sec. ============================================================================== Table 2: Recording Groups and Module Usage Summary: =========================================================================================== Bd Ft Hb Ho Ht Ke Kk Ma Ny On Ts Wf Ww Wz Yg Ys Zc =========================================================================================== C1401 0.9 1.7 1.8 0.8 1.4 2.2 1.7 1.9 1.6 2.3 0.9 1.7 2.1 1.3 2.3 1.4 0.9 ----------------------------------------------------------------------------------- B D D B B G D D D G B D G B G B B =========================================================================================== C1402 0.9 1.6 1.8 0.7 1.3 2.1 1.7 1.8 1.6 2.1 0.9 1.7 2.0 1.3 2.2 1.3 0.8 C1403 0.9 1.6 1.7 0.7 1.3 2.1 1.8 1.8 1.6 2.1 0.9 1.7 2.0 1.3 2.2 1.3 0.8 ----------------------------------------------------------------------------------- 1.8 3.2 3.5 1.4 2.6 4.2 3.5 3.6 3.2 4.2 1.8 3.4 4.0 2.6 4.4 2.6 1.6 D G G B G H G G G H D G G G H G D =========================================================================================== C1404 0.9 1.6 1.8 0.7 1.3 2.1 1.7 1.8 1.6 2.1 1.0 1.7 2.0 1.3 2.2 1.3 0.8 C1405 0.9 1.6 1.9 0.7 1.3 2.3 1.7 1.8 1.6 2.1 0.9 1.7 2.1 1.2 2.2 1.4 0.8 . . . . . . . ----- . ----- . . . . . . . . . . . . . . 3.6 . 4.2 . . . . . . . . . . . . . .

J ( 8.00 TB) L (16.00 TB) Notes: - Example (recording group C1408, C1409, C4110 for station Matera): + record session C1408 on the H module, then + record session C1409 on the same H module, and then + record session C1410 on the same H module. - Suggestions for handling disk module changes are provided at the end of this document. - Tsukuba will record on K5 disks and will convert the K5 format to Mark 5B. The Mark 5B data will then be e-transfered to a server at Bonn. - Each station has two spare modules allocated that can be used when a regular disk fails: Bd 2G Ft 2J Hb 2J Ho 2G Ht 2H Ke 2L Kk 2J Ma 2J Ny 2J On 2J Ts (2 K5 modules equivalent to G-size Mark 5 module) Wf 2J Ww 2L Wz 2H Yg 2L Ys 2H Zc 2G - An "extra" disk is normally inserted once recording has started on the last allocated disk for an experiment. This is done in case the the current disk fills early. Typically, this should be the module that would be inserted next if recording goes as planned. If nothing goes wrong, this will make it easy to transition to the next module/schedule. If a disk does fill early, the station will have to consider how to record the end of the next experiment, since some of that experiment's module will have been used to for the current experiment. Please also see the DISK MODULE CHANGES section below. Please inform the coordinating center (ivscc@ivscc.gsfc.nasa.gov) if a module fills prematurely. - Please use module sizes according to the latest distribution memo dated April 15, 2014. The modules you have on site allocated for CONT14 maybe larger than required, because the final schedule files were created after the distribution memo. If you have any questions please contact the Coordinating Center. ===================================================================== Recording mode Name Code GEOSX8N 8F Recording mode setup for: BADARY FORTLEZA HART15M HOBART12 HOBART26 KATH12M KOKEE MATERA NYALES20 ONSALA60 TSUKUB32 WARK12M WESTFORD WETTZELL YARRA12M YEBES40M ZELENCHK Mode Tot.Rate Tot.BandW #BBC #bits Barrel Mk341:1 512 Mbits 256 MHz 14 2 NONE Chan.BW #Subpasses Tracks(*fan) Tot.tracks Speed 8.00 MHz 1 32(*1) 32 0.00 X-band spanned bw= 720.0 MHz rms spanned bw= 280.4 MHz S-band spanned bw= 140.0 MHz rms spanned bw= 50.9 MHz Effective number of 1-bit channels recorded per sub-pass X S Total 19.13 11.48 30.61 ===================================================================== =================== DISK MODULE CHANGES =================== These experiments should only require one (or part of a) disk module each. Some modules will have two, three, or four experiments recorded on them. Stations should follow the assigned list of module sizes according to Table 2 in these notes. DRUDG does not know the sizes, so it shows an ever-increasing GByte count in the listings. Please be aware that for the second experiment on a module, the Byte Count in the listing will not reflect the volume of data on the module from the previous experiment. Here are four suggestions for handling the changes: 1) Planning: Select the modules you will use for each experiment ahead of time using the sizes in Table 2 above as a guide. 2) Changes: After the last experiment for a module has been recorded and recording has switched to a new module, change the old module as soon as practical. You should put in the next module that is needed after the new one that is currently recording. It is good practice to change the module as soon as possible because then the FS will have a module to switch to in case the one being recorded becomes full prematurely. You should check periodically during the experiments that the modules are filling at the expected rate. If a module does fill prematurely, a window will appear prompting you to change the module. The window will give both the VSN and bank that needs to be changed. You should dismiss the window once the module has been changed. In situations where you have a module fill prematurely, you will need to make a practical decision about the next module to put in. You will at this point be recording the rest of the current experiment on the module for the next experiment. It may be a good choice to put in a spare module that will allow you to finish recording the next experiment once the current module is full. Please be aware this may affect your plans for automated module changes and which modules will need to receive expedited shipping. 3) Labels: Label the modules before removing then from the Mark 5, also affix a red dot. This will help avoid mixing-up the modules. At a minimum, label the module with the experiment it was used in and its sequence number. You should be able to print a label using: cd /usr2/log drudg LOG_NAME VSN where LOG_NAME is the name of the experiment log, including the ".log" and VSN is the eight character VSN. It should be done whenever a module has been filled or a schedule has ended (in the case of a not completely filled module). This ensures that the label contains the correct informa- tion. The label should then be affixed promptly to help keep track of the module contents. If you are not able to print module labels and need help trouble-shooting this, please contact Ed (Ed.Himwich@nasa.gov). This issue can be worked on even after CONT14 has started. 4) Locking and unlocking: When inserting or removing a module, turn the latch to "locked" or "unlocked" only when the Mark 5 is not recording. In addition, do not turn the key to "locked" unless the FS will not be sending commands (either to setup or start recording) to the Mark 5 for at least 20 more seconds. An "unlocked" module can be safely slide in or out at anytime. If you have any questions, please contact Ed Himwich (Ed.Himwich@nasa.gov).
