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.

The experiment started fine and going ok. Modules' VSNs are inserted in the table.
Hb:
- Signatures of RFI in channels 14, 15
- High Tsys in S-band channels
- 2059 UTC: fmout-gps jumped to 0.25s. Mk5 rebooted to no effect. DBBC rebooted and module changed.
- 2202 UTC: Returned to schedule with normal clkoffsets. Scans 247-2059 – 247-2200b bad. Now recording to HOB+0129.
- 2320 UTC: Clock offsets drifting. DBBC rebooted. Previous module seems to be fine. Recording to HOB+0128 again. Scans 247-2059 – 247-2323b now considered bad
Ke:
- Signatures of RFI in channels 11,12,15
- High Tsys in S-band channels
Yg:
- RFI signature in ch 15
- S-band channels 09, 12, 13, 14 Tsys is a bit high
