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.

13:13 UT, field system at Katherine crashed. (Lucas)

  • Last scan before crash 290-1256, first scan after crash 290-1322.

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)

  1. Experiment started late (1830 UT) due to unresponsive PCFS and antenna stuck. Warren had to go to Mt Pleasant to fix the antenna problem (mas)
  2. Missed the first 10 scans (mas)

Hobart 12m

Disk VSN: flexbuffhb

  • 18000UT Experiment started okay (Prad).
  • Flexbuff stopped recording between 1945 and 2029 UT. Disks full.Jamie freed up space and the recording resjumed around 2100UT.

Katherine 12m

Disk VSN: flexbuffke

  • 18000UT Experiment started okay (Prad).
  • The flexbuff wasn't recording for the first 10 minutes. 'setupvgos' prompted the flexbuff to start recording. Missed 041-1800 to 041-1807b. Recording started halfway through 041-1810.
  • Large difference (~6 microsec) between maserdelay and dbbc3delay, also seen in DBBC3 output. related to maser instability (JMC)
  • Another jump ~05 UT (JMc)
  • 0543 - Halted schedule to resynch. Delays now returned to ~4 microseconds and offset from maserdelay be ~0.11 microseconds (JMc)
  • 0555 - Further jumps. Unclear if the frequency is also glitching or just the PPS. Continuing on as dbbc3delay readings seem stable (JMc)
