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.

Hobart 12m:
Disk VSN:HOB+1003/8000
Data volume at beginning: 0 TB
Hobart 26m:
Disk VSN: NTO-0007/2000 Data volume at beginning: 0TB
UT 17:58 - getting error Device vf timed-out on response from MATCN (JS)
Katherine 12m:
Disk VSN:USN-0091/4000
Data volume at beginning: 0TB
- 03:10 UT - Clock jump from -0.3 microsec to -0.48 micro sec in formatter - gps (vk)
- 05:20 UT - It looks as though the formatter to gps difference is slowly drifting to > |-0.48| microsec (vk)
- 06:04 UT - Halted schedule to reconfig DBBC as drift is > |-0.5|(vk)
- 06:24 UT - Restarted schedule. Missed scans 140-0604 to 140-0624, corresponding to 27 GB (vk)
- 07:29 UT - Clock jumps, missed scans 140-0728 and 140-0737 (Ross).

Jesse: I have edited the schedules so CRDS77 should start automatically after swapping to the correct module with a 1 minute delay (but you should definitely make sure this actually happens…) And cos I'm so nice, I even drudged the schedules for you, so it should roll straight over all by itself :) Well except for the 26m, you'll have to set that up. (Ellen)
Hobart 12m:
Disk VSN:UAO-0014/2000
Data volume at beginning: 0TB
- 17:00 UT - Experiment started ok
Katherine 12m:
Disk VSN:HOB+0128/32000
Data volume at beginning: 23297TB
- 17:00 UT - Experiment started ok
- 17:35 UT - Delay difference crept up to -0.5us. Ran fmset and fixed it. (Ellen)
- 21:29 UT - Delay difference again got too big. Restarted and reconfigured the DBBC since this time fmset alone didn't fix it. Missed scan 138-2140c as a result. (Ellen)
- 22:23 UT - Delay difference is drifting AGAIN. clkoff seems to be the culprit. (Ellen)
- 22:35 UT - Restarting DBBC again, since delay difference again reached -0.5 us. Missed scan 138-2236. Emailing Jamie… (Ellen)
Yarragadee 12m:
Disk VSN: NRCAN-09/2000
Data volume at beginning: 0TB
- 17:03 UT - Experiment started late due to network connection loss (in my sleep-deprived state it didn't occur to me to call the station and ask them to reset things until just before it was meant to start). Only missed scan 138-1700b. (Ellen)
- 17:06 UT - mk5=dot? returned value of almost -1. Ran fmset between scans and it came good, except the delay difference jumped 0.05us but is now steady again. (Ellen)
AOV003
Hobart 12m:
Disk VSN: GSFC+022/8000
Data volume at beginning: 6529 GB
- 10:00 UT - Steep slopes on several channels in the autocorrelation spectrum (vk)
Hobart 26m:
Disk VSN: NTO-0007/2000 HOB+0105/16000 (someone forgot to change the module, adding data to a recent Ke LBA run…)
Data volume at beginning: 11844 GB
- System temperatures are much too high (>1000). Liza has been working hard, but no solution has been found to this problem. Intermittent halting of schedule occurs between 01:30 and 02:00. Additionally, a formatter time offset became apparent and was fixed between these time ranges (Chris)
- 04:10: The “calu -m pcfs” command makes things a lot more sensible. Unsure of the data quality before this time. (Chris)
Katherine 12m:
Disk VSN: HOB+0128/32000
Data volume at beginning: 22764 GB
- Schedule starts late, due to aua008ke finishing after 00:00 UT (Chris)
- Scan 137-0000 (0202+319) missed
- 11:52 UT - Clock jump between 09:47 - 10:48 UTC in formatter difference. Jump from average of -0.35 to -0.425 microsec (vk)
- IFA, IFB, IFC – Tsys are high (110-155K) throughout the whole experiment (Liza)
Yarragadee 12m:
Disk VSN:HOB+0093/16000 USN+0220/8000/ (nope, someone forgot to swap the modules)
Data volume at beginning: 6912 GB
- Schedule starts late, due to aua008yg finishing after 00:00 UT, then aov003yg not being drudged (Chris)
- Scans 137-0000 through 137-0010 (0202+319, 2149-306, 1954-388) missed
- Scan 137-0013b has a bad autocorrelation - data may be useless (Chris)
Parkes 64m: VSN: PKS0018/8000
Experiment started OK
- Schedule starts late, because atsnap was not run with schedule= (Chris)
- Starts after 00:10 UT
- Corresponding scans before this time are presumably missed.
