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.

- 00:43 UT - During scans 154-0043 and 0044 got the following errors: WARNING: error an -103 pointing computer tracking errors are too large ; WARNING: error qo -301 warning: onsource status is slewing! Scans probably bad. (Ellen)
- Tsys bands 13, 14 consistently quite high. (Ellen)
- 0919 UT - S-band IF attenuators were at 10 db and AGC in ifc was overflowing. Ran ifnom to increase attenuation to 15 db in S band. (Dave)

- clkoff counter defect (gpib device inaccessible). time-out warning. Went to Mt Pleasant and at least could get the display back. Clkoff not working, manual reading necessary. (Lucia)
- 17:13 UT: LO unlocked, RF switches unknown. Restarted Monica, ok now. (Lucia
- 01:17 UT: LO reportedly unlocked, RF switches reportedly OK. Problem with the new version of RXMon, Jamie repaired it. Receiver was always locked. (Liza)
- 11.11 UT LO reportedly locked, restarting Rxmon and IFBox… All good! (Liza)

pointing repeated several times until good. (Lucia)
00:26 UT: “ fs restarted between scans 151-0018 and 151-0023 due to GPIB converter problem. Watch out for Warning WARNING: error ib -524 gpib/232 converter timed out, wt - THIS IS CRITICAL!!! (Lucia)
00:26 UT: rfpic restarted (Lucia)
02:20 UT: re-occurring warning ERROR s5 -104 rfpcn: time-out, connection closed. This is critical. Stop and Restart Rxmon on pcfshb. This problem seems to come back once every hour, always just past the full hour. (Lucia)
Hobart 26m:
Disk VSN: NTO-0007/2000/
Data volume at beginning: 154 GB
Date and time in erc wrong (1970) - we had this also when Alexander was here. (Lucia)
08:49 UT - Disc pos is steadily increasing ahead of where it should be … Currently ~45 GB ahead. (Ellen)
10:38 UT - Disc pos now ~ 50 GB ahead. (Ellen)

R1 Transfer behaved the entire time and looks like it finished happy. (Ellen)
UT 08:22: Pointings good for all 3 telescopes (JS)
UT 08:38: Fringes found in both(?) bands for all 3 telescopes (JS)
Hobart 12m:
Disk VSN: HOB+1003/8000/1024
Data volume at beginning: 5052.945 GB
- UT 18:27 Windstow active until: 18:31:16 scans missed: 148-1830b (JS)
- UT 02:50 - Halted schedule to restart DBBC. pps_delay value was drifting, which resulted in clock drift. Restarted at 03:06 UT. Missed scans 149-0251 to 149-0258a corresponding to a 7.3 GB deficit (vk)
- UT 03:18 - Restarting the DBBC seems to have worked and the clock differences are clustering at around -0.25 microsec (vk)
- UT 13:03 - Various errors from the pic and disc pos falling slightly behind (~25 GB) so I reset Rxmon. (Ellen)
Katherine 12m:
Telescope was involved in a survey recently, check extra carefully everything is ok.Ryan will be there in the morning Thursday sometime (might be early). Mick can go out to the telescope up until Friday lunchtime.(Brett via Anita)
Disk VSN: BKG-0049/2000
Data volume at beginning: 1.218 GB
Experiment started OK
Maser was very slowly drifting over the course for the 24 hours displayed, but stayed between -0.295 and -0.325. (Ellen)
Yarragadee 12m:
Disk VSN:UVLBI-13/2000
Data volume at beginning: 0.513 GB
UT 18:31 Waiting at limit at start of experiment, missed scan 148-1830b (JS)
Note: IF values were at S-RCP 15, X-LCP 7 I reset these to the nominal S-RCP 10 X-LCP 7 and the attenuations seem fine
e-control wasn't connecting but the new one (that we haven't used for aaaages) connects fine 
- 13:09 UT - I decided to try and use the new e-remote just so I could submit checklists. Unlike the normal one it runs, but very slowly. I went looking for Dave's backup version but Nautilus seems to have eaten all the desktop items again… Also the connection seems very flaky, dropping in and out all the time. (Ellen)
- 18:10 UT - Experiment ran over onto 2nd module: SHAO-020. So on VSN:UVLBI-13 there was ~1990 GB and 23 on SHAO-020 from this experiment. (Ellen)

Occasional error: “WARNING: error s5 -104 rfpcn: time-out, connection closed” (Anita)
Autocorrelation spectra for channels 4 - 7 are pretty slopey, and RFI in last 2 channels as normal (Anita)
- 06:28 UT - Scatter in formatter-gps time difference between -0.312 > t > -0.328, but more-or-less stable at approx. -0.320 (vk)
- 09:22 UT - pcfshb ran out of disk space. Fixed at 0937. No missed scans.

- 00:30 UT - Clock started to drift from 20:03! Scans 142-0030b and 142-0039 missed during dbbc restart, scans 141-2003 through 142-0028a may be unreliable (Ross).
- 00:49 UT - Clock still drifting, missed scans 142-0042a through 142-0057a too (Ross).
- 01:53 UT - Field system crash and failure to restart, missed scans 142-0101 through 142-0157 (Ross).
- 06:12 UT - Looks like a formatter to GPS time difference jumped from -0.27 to -0.29 microsec (vk)
