DX Commissioning

Setup

1:42
  • Pointing
1:55
  • Centering on P Cygni
  • GOPT ON
  • NCPA ON
2:14
  • Had to restart adsec, difficulty powering on
2:22
  • DX adsec finally setting.
  • I skip the "Check Flux" step in the preset because it complains about saturated pixels.
02:30
  • Gains are much more reasonable, I think...
2:44
  • Back on target.
  • 400 modes, GOPT etc running properly.
3:07
  • Had the pupil shift problem, but was able to reclose the loop quickly.
  • Optical Loop Data: 031057 a pause happened, 031125, 031137, 031202, 031227
03:17
  • Optical Loop data just after offset, to see how much the camera lens is off.
  • 032157 small offset, false alarm
  • 033226
  • Another big offset: 042053
04:48
  • Failure on an offset, causing the subsequent offset to fail.
5:27
  • Starting AFC.
05:36
  • A quick note, while we are waiting:
  • The DX shell does seem to be somewhat unstable on the damaged edge.
  • The loop can easily compensate, but that edge always looks like it wants to roll.
05:46
  • Centering pupils on the guide star.
  • Optimize gains overdrove the first time
  • The script kept running and I re-closed and re-optimized.
  • GOPT is running. NCPA is irrelevant and it's more stable without it, so...
06:03
  • Dataset: 060339
  • GOPT ratio went to 0.01 briefly and mad the correction poor.
06:08
  • Looking into the (mild) wind. There is a bit of vibration visible in the data set.
  • Dataset: 060934, I increased the TT gain.
06:25
  • Going well on my end. Jochen is having troubles with the rm525 computer.
  • He will be trying to use an OpenNX client.
06:29
  • Still a lot of vibrations: 062909
  • 063827
06:32
  • We will be going to a different source.
  • Mon Sep 25 07:05:41.991 2017 aos.warning - FLAO: Error for Variable: AOException: Error writing variable - -5001: Timeout error

    Mon Sep 25 07:05:42.501 2017 aos.warning - FLAO: Connection with RTDB lost

    Mon Sep 25 07:05:59.526 2017 aos.warning - FLAO polling disabled after several attempts

    Mon Sep 25 07:06:03.813 2017 aos.info - FLAO subsystem polling enabled

    Mon Sep 25 07:06:03.926 2017 aos.PresetAO{FLAO}.failed - PresetAO {FLAO}[1196] - [AOException] SelectFocalStation: WARNING - adsecarb:Illegal command for state AORunning (Set focal station)

07:12
  • It seems that if one tries to stop processes to make a preset fail, everything dies, and I mean EVERYTHING, EVERYBODY, ALL MORTAL LIFE.
  • Adsec became disconnected, too. Possibly related.
07:29
  • Preset is proceeding
  • Dataset: 074213
  • Much better vibration situation.
08:24
  • Repeating preset due to problem with AFC procedure.
  • No GOPT, bin 3.
  • Dataset:082552
  • Low vibrations
08:48
  • Bin 4 preset, 200 Hz
  • 084834
  • Vibrations not so bad.
10:38
  • Dataset: 103821, 104330
  • a lot of safe skips, maybe actuator 338?
  • 105210
  • The camera lens seems to be moving the pupil images in the vertical direction, is this the reason for the skip frames?
  • Mon Sep 25 11:15:52.648 2017 aos.Pause{FLAO}.failed - Pause{FLAO}[1147] - Command interrupted

12:17
  • Trying an ESM preset.
  • Smooth as glass, except optimize gain made the gains very high. I manually reduced them.
  • Datasets: 122756, 122811, 122826, 122839
  • Camera lens in bin 4 still wants to march the pupil to the top of the frame. I think that it's due to the background levels.
  • 124139, 124153, 124209, 124228
