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.

Disk VSN: MPI-0510/4000 | Data volume at beginning: 0.19 GB
- 1700UT Experiment started okay (Lucas).
- 22:00UT Disk position lagging considerably with a loss rate of approximately 12 GB/hr when the whole experimental rate is approximately 145GB/hr. So almost 9%. They're aren't any late-source events of missed scans so far so I'm wondering if there are dropped bits aka are the mark 5 recorders not doing a good enough job? (Lucas).

- 1730 UT getting erroe for wth command- Problem connecting to metserver socket. (Jay)
- 06:20UT - RXP command is broken for the 26m. It returns incorrect values in the field system. Need to use the receiver coordinate readout on the webcam instead. (Patrick)
- 06:23UT - Receiver was configured in 'crossed' mode, not 'direct'. Fixed this as of scan 086-0629a. NOTE THIS IN THE end-of-experiment EMAIL (Patrick)
- 06:30UT - clkoff & maserdelay commands not returning any data. Fixed by running clkoff & masedelay in the hb field system. (Patrick)
