SX NCPA Measurements

02:00 Get started

02:30 Trouble getting the OptGain loop to close (find signal)

03:00 Even from AOS PresetAO, which loads in the needed disturb

04:43 Alfio has us change the CCD39 Repetitions from 61 (default) to something
  • 55 is good

04:53 Very large vibrations on the telescope as seen on LUCI1 image. Long sausage

04:53 Generate an astig for OptGain with 20nm amplitude
  • 20160316_165303
  • No difference, OK and KO

05:04 Astig with 10 nm amp and 187 Hz
  • 170446
  • No Differencem OK and KO

07:02 Make TWiki output
  • set1=obj_new('aodataset', from='20160316_183630',to='20160316_183800')
  • log_twiki, set1
  • add , /rec to obj_new request to force a recalculation

07:12 make modal plot for high strehl set at 210 degrees 20160316_183810
  • 1.2" seeing = 51%

07:27 create disturbance
  • 20 nm astig
  • 1.5"/2
  • 192714

07:33 Long exposure
  • 200 frames
  • 1.5"/2
  • 20 nm astig
  • 193243

07:40 "Trefoil" test, 10 nm astig

07:40 Disturbance + 10 nm astig
  • 20160315_183311 3.0"/2
  • 20130315_183527 2.4"/2
  • 20160316_194138 2.0"/2
  • 20160316_194419 1.5"/2

07:42 Disturbance + 20 nm astig
  • 20160316_194833 3.0"/2
  • 20160316_194658 2.4"/2
  • 20160316_194606 2.0"/2
  • 20160316_194533 1.5"/2
