  • ESM target
  • Magnitude shows 15.9
  • Gains are 0.42, 0.47
  • Bin 4, 296 Hz
  • 20220318_025250
  • Seeing between 1.15" and 1.3"
  • Winds are staying below 15 or 16 m/s.
  • AO winds are below 2 m/s (the wind is at our back).

  • ESM target.
  • Mag 16.6
  • Bin 4, 200 Hz
  • Gain: 0.94 0.76
  • 20220318_033023
  • Winds still staying below 15 m/s

  • ESM Target
  • Mag 15.4
  • Gains 1.01 0.31
  • Bin 4, 400 Hz
  • 20220318_042833
  • Winds around 10 m/s
  • AO winds around 1.5
  • Seeing 1.0" - 1.35"
  • Still having issues where there are safe-skips at the end of an offset, as if the offset doesn't quite reach the correct position, or the loop closes before we are ready.
  • housekeeper.L |INF| 1614340|2022-03-18 04:36:13.666984| SwitchSafeSkipFrameCnt > 20568

  • You can see how much the camera lens has to move at each offset.

  • PSF Star for the previous object.
  • Mag 15.9
  • Gain: 0.99 0.60
  • 20220318_053750

  • Next Target
  • ESM
  • Bin 1, 400 Hz
  • Gain: 10.8 13.74
  • 20220318_061708
  • The seeing blew up and we lost the source
  • It took a while to get the source back and the seeing blew up some more.
06:40
  • One last object to try, just to see if the seeing is better in a different direction.
  • Rerotator at the limit, rotating to + 200 and re-sending the preset.
  • Bin 3, full AO
  • 293 Hz
  • Seeing jumping too much, we're stopping.
