OSCO in Twilight then IP-Tau

00:45 Josh gets the WFS power on and starts cooling the OCAM

01:50 Bin 1 OCSO had a failed optimize gain. Set gains manually.
  • see a bit of high forces at 9:00.
  • Move re-rotator +1 degree. a few skip frames.
  • Move re-rotator -1 degree. Many skip frame
  • Move to +0.3 and seems good. I didn't change offset value in wfsarb.conf, small change needed.
  • skip optimize gain
  • Optical gain failed. I still have re-rotator off. Turn it on
  • Optical gain succeed.
  • See some skip frames
  • LUCI waiting for collimation because it took too long to press Done.
  • Move on to IP Tau

02:00 Collimated on nearby Off-axis star
  • Blind AO preset
  • Optimzize gain end and skip frame, loop open
  • Next Opt gain ok, optical gain and NCPA
  • Go to LUCI
  • TN 021218, 022244, 023815, 024838, 025833
  • Bin 2 loop just closed
    bin2_start.jpg
  • High force at actuator 224
    bin2_start_force.jpg
  • After 20 minutes get ring patter in current (scale the same as above)
    bin2_center_rings.jpg
  • Modal plot
    bin2_modal.jpg
  • Later forces on actuator 232
    bin2_later_force.jpg
  • Negative force at actuator 478
    bin2_neg_force.jpg

03:10 Still bin 2 IP Tau
  • Had maybe five minutes where we were getting bursts of skip frames. Up to 70% for 2 seconds and then none of 20 seconds.
  • LUCI images look OK
  • Modal plots look OK
  • TN 031037
  • Now no skip frames

03:13 Loop in PauseAO state.
  • skip frame bar at 100% and Red

  • Loop Resume, skip frame, StopAO
  • Loop closed again from FLAO GUI
  • Set gains to previous values
  • GOPT on
  • NCPA on
  • Back to taking LUCI images

  • Bayside stages at -78.66, -40.07
  • Move them to -78, -53 and see the star
  • re-close loop but skip frame and StopAO
  • Re-close loop and ok
  • Manually set gain
  • Gopt
  • NCPA
  • All is good
  • Start LUCI script
  • Offset to same place (script thinks less than an arcsec but Y stage move 15 mm)
  • No start Resume Fail, etc
  • Do loop closure again
  • Same problem. Olga said it looked like LUCI script did all offset but no images, in just a few seconds) LUCI script problem?
  • Also, earlier a filter change by LUCI would reset image to full frame. Olga had to set to sub frame after every offset.
  • Gave up and send Preset again
  • Seems to be working now.
  • TN 044406, 044453, 044551 (some skip frame, everything looks good

  • seems we did not receive a ResumeAO
  • Only off the tip of the pyramid by 0.2 mm
  • Another offset. same thing
  • This time off by 7 mm

05:10 New bin 3 target
  • Loop closed ok
  • Optimize gain only ramp TT and HO1. HO2 ignore (left at 0.1)
  • After Optimize gain I set HO2 to a little below HO1
  • slope RMS seemed to get a bit smaller
  • Ask Enrico and Alfio
  • bin3_optimize_gain.jpg:
    bin3_optimize_gain.jpg
05:51
  • Greg has taken over.
05:58
  • adsec in failure after trying to re-close the loop.
  • Re-sending.
  • adsec kept failing
  • Guido came on and we determined that actuator 486 was reading 35 microns when the shell was set.
  • We removed it forthwith.
  • Changing to seeing limited.
