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.

Hobart 12m:
Disk VSN: HOB+0118
Data volume at beginning: 2507.301 GB
- 18:00UT Exp started OK. First source was 0834-201. Antenna checks and fringe check not done, due to time constraints.
- 00:27UT Wind stow. 23:39-00:07. (Lucia)
- 00:40UT Wind stow. Antenna changes frequently between stowing and operating now. Need to extract all stowing times using Arwin's script once the experiment has finished. (Lucia)
Katherine 12m:
Disk VSN: USN+0225
Data volume at beginning: 2074.354 GB
- 18:00 UT Exp started OK. First source 0834-201. Antenna checks and fringe check not done, due to time constraints.
- 07:35 UT Noticed that the met sensor is stuck - has been reporting the same value on weather checks since experiment start. Called Jamie - fixing in 30 mins. Unreliable weather data prior to fix (Bryn) (note: correct weather data is from 11:23 UT onward! -Tiege)
- 15:00 UT Attempted to switch module in between scans, unfortunately the new module was in read only mode (error: error m5 -900 bank is write protected) , called Jamie, he was able to fix it using “mk5=protect=off” and “mk5=reset=erase”. BEWARE: If you are looking back at these handover notes after getting the same problem, I am assuming “mk5=reset=erase” fully wipes the disk, make sure the disk is empty (not that this is likely to occur if the disk already has data written onto it) before going ahead. First scan on new module is 033-1521, however, only latter part of scan is valid. Missed scans are 033-1503 to 033-1517 inclusive. (Tiege)
Yarragadee 12m:
Disk VSN: HOB+0076
Data volume at beginning: 0 GB
- 18:17 UT Exp started late, mk5 had crashed and needed a few power cycles before it came back online. Fist scan should be 032-1822 and the source 0537-441. data offset 121.5 GB.

- 0216 - 0236 Windstowed. (JMc)
- 09:37UT During scan 031-0938 the power for the media converter died. Required me to drive out to the telescope and call Brett who talked me through it. (JR)
- 10:52UT antenna control restored. Scan 031-1058 should be OK. (JR)

- 15:00UT Reconfigured DBBC as the auto correlation spectra wasnt very good. (Arwin)
- 17:00UT Exp started OK. First source was 0727-115. (Arwin)
- 19:53UT Delay difference changed a bit, keeping an eye on things. (Arwin)
- 22:12UT Delay difference jumped. Power cycled the DBBC, schedule resumed 2228 (JMc)
- 13:45UT Antenna stuck and had to reboot drive system, missed scans 031-1343b to 031-1351 (Ross)

- 15:00UT xRCP is different (should be 7, is currently 0), though the target power levels were reached easily, not sure if this is a problem? (Arwin)
- 17:00UT Exp started OK. First source was 0727-115. (Arwin)
- The power level has been set to the default value at end of experiment (Ross)

Hobart 26m
Disk VSN: HOB+0025
Data volume at beginning: 775.920 GB
- 17:15UT getting error qy -1 error in response from counter. Tried restarting with 'counter' command. No response when issuing clkoff and maserdelay commands. Called on-call (Warren), to attempt to fix (Bryn)
- 17:30UT experiment started on time.
- 17:37UT WARNING: error ib -4 gpib device time-out on response ca. Error likely related to previous, trying to reset with counter does nothing. Manual reset of GPIB device might be needed (had a similar issue to this a few months ago) Waiting until staff on site to fix. (Bryn)
- 0829UT Large delay (~0.98 us) fmset issued between scans (JS)

- 17:00UT - Experiment started OK (Tiege)
- 08:33UT auto correlation spectra is not as “clean” as the other two stations. Channels 1,5,8 and 12 are not flat. Will keep an eye to see if something needs to be done (Arwin)
Yarragadee
Note keep an eye on the disk here, summary file states the experiment needs 4005.7 GB, disk its recording on to is 4000 GB, because the total amount recorded is always behind by >5.7 GB at the end of an experiment, I kept it on this disk.

Yarragadee 12m
Observer: Arwin
Summary
- The signal observed was very strong and the peak was very wide (see figure below, normally we center the peak at 800 mhz and set the span to 20 mhz, this time I needed 100 mhz). I was worried that the signal might be saturating and unable to get in touch with Jim, we tried changing the variable voltage to see if it has an affect on the signal strenght.
- 20:30 - 21:15 UT 14 -rfpic=cross,direct
- 21:15 - 21:27 UT 10 -rfpic=cross,direct
- 21:27 - 21:35 UT 20 -rfpic=cross,direct
- Unable to see any change in the signal strength on the spectrum analyser, we tried to change the modes
- 21:40 - 21:42 UT 20V? -rfpic=cross,cross
- 21:42 - 21:46 UT 20V? -rfpic=direct,direct
- 2146 onwards 20V? -rfpic=cross,direct
