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.

It is ESSENTIAL to put your name after EVERY entry. Copy and paste the template into the new handover notes

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.

  • 1800UT Experiment started okay (Lim)
  • Several brief windstows between ~0000 and 0400 UT (JMc)

Katherine 12m

Disk VSN: flexbuffke

  • 1806UT Experiment started 6 minutes late (Lim)
  • “TCP/IP connection closed” multiple times (Lim), a few scans might be shorter than the scheduled length.
  • 0030-0430 No recordings after power interruption(?) and network error. preob procedure did not include the “runtime” command, leading to incompatible format issues. No alarms raised by log monitor, though error was active (JMc)
  • 1645 UT, received a continuous error “ Error st -999 tcp/ip connection was closed by remote peer”. Had tried to reboot the drive, but the antenna still failed and stuck till the end of the experiment (1800 UT) (mas)

  • 2347UT no s band recorded before this time (wiki needs updating with new setup script), halted for reconfiguration of dbbc3ke. First good scan 061-2354 (Lim).

  • .0209 UT edited setupsx in procedure file, had been copied from aum018 (as per wiki) with wrong mode. Had inherited 16 channel from previous r1? Changed to 32. (warren)

Hobart 26m

Disk VSN: MAT+004 | Data volume at beginning: 2102.4 GB

  • 1800UT Experiment started okay (Patrick).
  • 2255-0010 Windstow (JMc)
  • Tsys values seem high, IF power apparently low. Might be an issue with amplifier gains causing loss of sensitivity. Will investigate tomorrow (JMc)

Hobart 12m

Disk VSN: flexbuffhb

  • 1800UT Experiment started okay (Patrick).
  • ~2300-2328 Windstow. (JMc)
  • 0234 PCAL on. (JMc)
  • 2200 UT (after experiment) - Noted that sampler 3 is reporting poor statistics. Check the dbbc log!
  • ~1530 - Sampler 3 (X-band.X-pol) lost lock.

Katherine 12m

Disk VSN: flexbuffke

  • 1800UT Experiment started okay (Patrick).
  • 2300 UT - Samplers show poor statistics. Stopping to reconfigure (JMc)
  • 2312UT - Back on schedule (JMc)
  • NB - Sampler 2 statistics are “Bad”, but still getting good performance. Carrying on for now (JMc)
  • 0234 PCAL on. (JMc)
  • Sampler 3 intermittently reporting as “Bad”. Still seems ok, so not trying a reconfigure. Issue seems to be the correlation statistics near to 170E6, Will need to address this if values go below 165E6 (JMc).
  • Samplers lost lock ~1320 (JMc)
