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.

DBBC software needed a couple of restarts due to the well known TPI overflow issue when doing a pointing check.
- 17:00UT - Experiment started OK (Tiege)
- 13:20UT - Network connection between ops8 and pcfsyg down. Can't connect to yg-via-internode. Monitoring, in case it comes back up. (Patrick)
- 14:20UT - Network restored. Contacted Yg and checked everything was operational on their end. Asked them to reboot/power cycle router, but they weren't sure which one (neither was I). Just about to call on-call person, then it came back up. (Patrick)

- Note: Record using jive5ab, please do not start DIMnino during next experiment setups or it will crash the mk5. If need to use dimino, go to pcfsyg and ctrl+c on the upper right terminal and run pkill jive5ab before starting it.
- TPI overflow problem again on pointing check. Restarted dbbc software a few times, dbbc=pps_sync sent a few times, didn't work.
- 1700UT Experiment started okay (Lim).
- 1700UT error m5 -900 not whilst recording and error m5 -906 mark5 return code 6: inconsistent or conflicting request seems to happen on every scan.
- The above error is due to mk5=bank_set? being called during midob. Commented out mk5=bank_set? in midob and moved it to preob. Temporary fix documented here (Lucas)
