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.

  • 1700UT Exp started OK. (Arwin)
  • 1700Ut still getting those rfpc errors but this is a known problem. (Arwin)
  • 23:00 UT Slave azimuth drive not working from experiment start until 23:13 UT . Slave was running for pre-experiment checks, but not at schedule start. Still tracking and slewing to source on master azimuth drive. May have affected pointing accuracy until problem fixed at 23:13 (Warren)

  • 1837UT Experiment started late due to drive failure. First good scan 138-1837a. Drive status kept tripping to not ready, and while the drives were on they would not go into operate. Eventually fixed by following procedure for when 12m drives get stuck after wind stow from current issues. Not sure if cause was related, there was no wind or wind stow…(Liz)

Listed as tag along for this experiment. May join if Warren and Brett finish what they're doing. (Liz)

  • Experiment started at 0628UT with 139-0628 (Ross)
  • 0724Ut Antenna waiting at limit for 139-0716b and 139-0718b, out of concern for being stuck antenna was stowed then sent to scan 139-0730a early. So missed 139-0716b to 139-0727 incl. (js)

  • 1800UT Got a Large Difference between formatter and maser delay (11.023 us), but fmset clock values all fine - VC rack is happy. (Bryn)

  • 1800UT Experiment started OK (Bryn)
  • 0000UT getting the “s5 -112 rfpcn: EOF pre-draining input, rfpic probably crashed, connection closed” errors persistently, these are due to the hardware failure of the PIC unit in the telescope pedestal, unlikely to be resolved without hardware replacement, as noted in the previous experiment. (Arwin)
  • 0000UT if the beeps get annoying, the above error can be (i think) silenced by “tnx=s5,-112” in the fs or erc. However, you'll need to terminate the fs at the end of the experiment, probably not until this is fixed anyway. (Arwin)

  • 1700UT Experiment started with rfpcn time-out error, have tried restarting Rxmon and Monica numerous times and error is still persisting. Also getting some clock drift. Experiment halted until things are fixed (Tiege)
  • 1730UT Have tried any solutions mentioned on the wiki, usually after 2-3 Rxmon restarts this problem comes right, however, this time it is lingering along with other issues cropping up. The following error “WARNING: 0 : 0x03040003 : 1028 : interrupts error from mark-5b dim or dom ;” has also displayed. I am going to restart Dimino (again) and make sure there are no other funky processes running on mk5hb. (Tiege)
  • 1758UT Experiment has started, however, rfpcn time-out is still being displayed at the start of every scan, I am hesitant to miss any more scans as the rfpcn time-out may be related to the other monica issues people have been reporting. In total I tried restarting Rxmon and monica 6 or so times each, ended dimino process and setup the experiment again, reconfigured dbbc, restarted dbbc, restarted/reconfigured dbbc and mk5 together. (Tiege)
  • 1805UT Seeing the clock drift again (in addition to rfpcn issues) has drifted from 0.260 us to 3.09 us over past 15 mins. going to attempt to fix this now. Experiment being halted again. (Tiege)
  • 1811UT Cycling power to mk5hb and dbbchb (Tiege)
  • 1817UT DBBC came back fine, though mk5hb has not come back from ipswitch power cycle. (Tiege)
  • 1830UT After multiple power cycles, mk5hb is accepting connection now, I have terminated the ds and re setup the entire experiment. First scan will be 135-1841 (Tiege)
  • 1841UT First scan and rfpcn time-out error has still occurred, completely out of ideas now and can not make contact with Jamie. Will monitor to see if clock drift continues to occur, otherwise I am going to leave rfpcn issue as is for now. (Tiege)
  • 0110UT Jamie has had a look at the rfpcn issue, he comments are that he believes the PIC in the pedestal is no longer answering queries, he thinks it may need to be replaced by Eric. He has disabled the rfpic command in the midob procedure (for this experiment) so the rfpcn errors will not occur. (Tiege)
  • 0552UT mk5hb crashed, I loaded a module into the non-active bank while it was recording data to the active bank, restarted dimino and got it going by 0607UT. Comments.py will pick this up automatically (hopefully). Scans affected 136-0552 (inclusive) to 136-0612 (not inclusive).(Arwin)

Antenna maintenance, new cable wrap resulted in late start. Encoder moved, and hopefully corrected for. Pointing checks done quickly, no time for full model. (Warren) Fivept result offsets 0.03, 0.01, (Az, El) see log.
