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.

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

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: Flexbuff-2hb

  • Reset, Reconig and finally Power cycled dbbc3hb couple of times, but 2-3 delay corr are still continuously bad. Can't do much at this point.
  • 1814UT Experiment Started late because of flexbuff recording issue. it wasn't doing doing the recording. Had to kill the fs and restart it again. after that flexbuff was happy and started recording. Weird issue. (Jay)
  • 2240UT: IFA/IFB changed to record S-band data - previously had been connected to the 3-7 GHz VGOS band. This was toggled through the pduhb.phys.utas.edu.au web interface (JMc)
  • ~2350UT - delays have gone bad. Schedule halted ~0012 for reconfiguration (JMC)
  • 0058UT - First good data after resuming. (JMc)
  • ~10:30UT - DBBC3 error and reconfig, sched resumed (Earl)
  • Same dbbc arose now for both hb and ke… (Earl) - attempted fix, but first go apparently none-too-succesful
  • 12:15UT - Dbbc Hb error again… (Earl)
  • 1327 same dbbc issue seems to be persisting, almost all power stats are bad. DBBC3 reconfigured but doesn't seem to change for the better (Jasper).
  • 1345 experiment resumed but have messaged Jamie over issues (Jasper).

Disk VSN: Flexbuffke

  • {Same as Hb} After Reconig and finally Power cycled dbbc3ke couple of times, but delay corr for IF 'F' is still bad.
  • 1817UT Experiment Started late because of flexbuff recording issue. it wasn't doing doing the recording. Had to kill the fs and restart it again. after that flexbuff was happy and started recording. (Jay)
  • Recorded file labels are inconsistent (a,b,c,d rather than sx,sy,xx,xy). Due to multiple datastream definitions. setup procedures editing to avoid this issue in the future.
  • ~10:30UT - DBBC3 error and reconfig, sched resumed (Earl)
  • Same dbbc arose now for both hb and ke… (Earl) - attempted fix, but first go apparently none-too-succesful
  • 13:00UT schedule halted when I logged in, resumed (Jasper).
  • 13:27 same dbbc issue seems to be persisting, power stats are bad. DBBC3 reconfigured but in doing this the field system refused schedule=aov063ke say it couldn't load it while it was executing from the schedule library. I let it sit for a bit to no avail so I restarted the fs-aum. Connection to the antenna seemed to be down. Repeatedly setting antenna=open worked but it took a while (Jasper).
  • 1500UTC system is recording again but IFC power and IFF correlation stats are bad (Jasper).
  • 1530UTC I noticed it wasn't recording, halted, killed jive5ab and reran setupaum as outlined in setup notes, this did the trick (Jasper).

  • 1800UT Experiment started okay (Jay).
  • 13:30UT received message “Large difference between formatter and maser delays, check the stability off new offset”. This only occurred once but I wasn't able to find when or by how much. maserdelay and clkoff seem ok before and after this.
