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.

- During setup, noticed yg had large offsets in the antenna checks, had to the the pointing checks again and the offsets were better the second time around. This has happened a few times, should this be raised at the meeting? (Arwin)

- 23:30UT - Schedule file was not being produced with the slogit script, Jamie drudged it manually (Patrick)
- 00:00UT - Experiment started OK (Patrick)
- 05:17UT - ALARM: error fl -1 previous source in this schedule not reached before new source was commanded (Patrick)
- 05:48UT - WARNING: SX receiver parameter pres out of range. Use rxmon command to confirm. Reported receiver position: X: -255.8mm, Y: 252.2mm, Z: 18.6mm. Called Jamie and he says if live page shows correct values (which it does) it's all fine (Patrick)
- 05:50UT - Vacuum pressure leak for receiver cooling system, can't fix for this experiment. Notified Brett, will try to fix on Monday. Rest of experiment will run with warmed receiver, from scan 280-0552 or so. (Patrick)

- 00:00UT - Experiment started OK (Patrick)
- 13:10:03UT ALARM: Large difference between formatter and maser delays. The times all seem stable and synced in fmset (Ross)
- 13:37UT Been cautious and reconfiguring dbbc incase delays are actually screwed, not justt shiftted to the next pps or something. Missing scans 280-1337 through 280-1345 (Ross)
- 13:55UT Noticed temperatures are not working, time cannot be resynched though, running with a delay difference of -145 seconds but synerr_eq_0. Missed scans 280-1358 through 280-1403 (Ross)
- 14:03UT Jamie is having an attack! First good scan 280-1420b (Ross)
