Handover notes
Please use this page to write up any notes on anything that needs to be passed on to the next observer or should go into the end of experiment message.
Notes should be placed below the horizontal line as a new blog entry.
Continuing problems should be copied to the Current Issues page.
**Template for Handover notes:**
Be sure to add any specific notes about the experiment if required, for example “Special back end configuration for x reason”. Put as much detail as you can - the more the better.
====== Experiment Name ====== **Hobart 12m** Disk VSN: abc-123 | Data volume at beginning: 2.34 GB * 1300UT a comment from me (user) **Katherine 12m** Disk VSN: | Data volume at beginning: GB * **Yarragadee 12m** Disk VSN: | Data volume at beginning: GB * 1300UT Experiment started okay (JMc).
Format for entering a comment It is important to stick to this formula - there is a good reason we need this information, so please include it!
Time stamp in UT * Comment * (Your Name)
For Example:
20:00UT: Wind stows, Missed scans 012-3456 to 012-3457 (Jim)
20:50UT: Mark5 lost connection, had to restart Mark5 and reconfigure DBBC, called Jamie on call to fix, missed scans 012-3456 to 012-4567 (Jim)
Again - as much detail as you can. It is important to remember that these notes will be sent to the correlator, so please make sure they make sense to others.

- 16:15 UT can't connect to mkv, calling on-call (Warren) to assist. (Bryn)
- 16:50 UT new module in mkv, can connect, but can't start up Mark5A. Warren restarting mkv. (Bryn)
- 17:00 UT running setupsx causes several errors:
- ERROR sp -13 This command not supported for your equipment, check equip.ctl
- ERROR df -201 Mode must be one of: astro, geo, wastro, test, lba, astro2, or astro3.
- ERROR di -400 IF module position exceeds number of conditioning modules
- ERROR q* -201 Channel must be loa-d: VLBA/4/5+DBBC, lo1-3: MK3/4/5+K4, lo1-4: LBA/4+all others
- 17:20 UT tried switching procedure to AUG031 and rerunning setupsx, gave same errors (Bryn)
- 17:45 UT fixed errors by switching to correct ctl files (Bryn)
- 17:59 UT Recording started with source 0834-201, scan 311-1759 disk pos lagging 97.7 GB. (Bryn)
- 14:40 A few gpib device time out errors. Running
counterseems to have fixed the issue. (Arwin) - 1524 UT rxp not responding. Though the live page is reporting the right receiver. (Arwin)

- 1520 UT Seems like the wrong module is listed above for katherine. It is currently recording to USN-0198 which is also about to run out, no mention of when it swtiched? (Arwin)
- 1547 UT halted schedule, all loaded modules are full. Martin is on his way. (Arwin)
- 1612 UT new module in but wont start the schedule as the r1 needs to be on a module by itself. Will miss the last 20 mins

- 1257 UT Randall at yg station inserting another module which sent mark 5 to a werid state. Got errors which are not listed in wiki (Arwin)
- 1327 UT Mark 5 came right after a power cycle. Scans missed 312-1257- 312-1329 (inclusive). Missed about a 100gb which explains why disk_pos is lagging by approx 200 gb. (Arwin)
