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.

* pre-obs: drives failed to operate again during pointing and initiating schedule, was az slave inactive in hmi causing issue. Reset the drives each time and all was good.

  • 1730UT - Experiment started OK. (Tiege)
  • 1730UT - Same rfpic issue as expected, should not have any impact on data, waiting on hardware for fix. (Tiege)

  • 1730UT - Experiment started OK. (Tiege)
  • 1745UT - Following error: “m5 -104 mk5cn: time-out, connection closed”. Everything seems fine with the mk5 currently, it is accepting all commands and appears to be running correctly, if the error triggers again I will restart DIMino. (note: it did not occur during recording) (Tiege)
  • 1932UT - Same error happened again. This time Autocorrelation spectrum is all over the place. Halted schedule, restarted DIMino and restarted schedule. Missed one scan 143-1937, first scan back is 143-1944 (Tiege)
  • 2117UT - mk5cn time-out has happened again. No faulty autocorrelations this time, Overwhelming majority of comments about this error on the wiki suggest it is a benign. Going to leave it unless I see it breaking things. (Tiege)
  • 0321UT - mk5cn time-put during scan 144-0320. No faulty autocorrelations appeared. As per above likely benign, however documented all the same (Jonny)

note: called Yg and they told me to put this experiment on same module as R1 from previous experiment as they are running low on modules

  • 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 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)

  • 1730UT Experiment started OK (JS)
  • 1750UT through 2220UT Getting consistent tsys overflows in vd, ve, i2, i3. unsure if this is an issue as tsys measurements are ok as are power levels (JS)

  • 1730UT Experiment started OK (JS)
  • 1932UT (and 2220UT) ongoing errors
    ERROR s5 -112 rfpcn: EOF pre-draining input, rfpic probably crashed, connection closed

    likely unsolvable without hardware replacement according to Jamie (JS)
