  • Gains 0.68 0.40 0.11 (Tiger Striping if HO2 is higher)
  • 182823 182836 182854 182922

18:31
  • Trying 300 mode reconstructor, same turbulence file.
  • Gains: 0.77 0.40 0.15
  • 183416, 183437, 183455, 183512
  • Not so hot

18:49
  • LUCI is now working
  • Same gain and disturbance parameters as before
  • 10 Luci Frames
  • 185124, 185159, 185223, 185245
  • SR 0.42

18:55
  • Back to 400 mode reconstructor
  • Gain 0.75 0.40 0.15
  • 185546, 185605, 185630, 185652
  • SR 0.44

  • Gain 0.75 0.40 0.30
  • 190612, 190656, 190750, 190819
  • SR 39

19:16
  • Bin2 is stable with /local/aomeas/adsec_calib/CMD/disturb/atm_1.6seeing_1000Hz.fits
  • Gains 0.48 0.62 0.58
  • 191858, 191923, 191959, 192024
  • Lots of vibrations all of a sudden.
  • SR only 21, but psf is elongated due to vibrations

19:31
  • Stability check
  • Since we are double pass, the seeing values will be halved
  • Bin 1, 400 modes.
  • /local/aomeas/adsec_calib/CMD/disturb/atm_3.0seeing_1000Hz.fits
  • It's stable
  • Gains 1.06 0.40 0.40
  • 193523, First one had too much tip/tilt 193652, 193754, 193815
  • SR 21
  • I think that there was something wrong with the other disturbance files, This one looks fine

19:43
  • Bin2
  • Same gains as above
  • 195257, 195317, 195339, 195401
