Phase III Active Optics at RFBG

05:00 Start measurement of zernike factors on RFBG.
  • preset
  • WFSC FWHM ~0.7
  • Before z12-22 corrections Guider FWHM ~0.8
  • Turn on high order zernike corrections in IDL.
  • After z12-22 corrections Guider FWHM ~0.6

06:05 DX zernike_collect, "sext_12_21_zern.list", /VERBOSE, EXP=15.
  • /home/dlmiller/data/20130325/zernike_gains/rfbg
  • measured Z4-Z22

?:05 SX zernike_collect, "sext_4_22_zern.list", /VERBOSE, EXP=15.
  • /home/dlmiller/data/20130325/zernike_gains/lfbg
  • measured Z4-Z22

?:05 SX zernike_collect, "sext_makeup_zern.list", /VERBOSE, EXP=15.
  • /home/dlmiller/data/20130325/zernike_gains/makeup
  • measured Z11, 16, 17, 18

12:35 preset to BS9169 with GCS Act Opt
  • w/o z12-21 corrections.
  • Clear Active Optics on the Primary.
  • With IDL collimating with Z12-21 we had ~0.6 fwhm on the WFSC
  • start at about image 122
  • Converge to ~0.6" fwhm on WFSC, same as with Z12-21. Only 228 nm of z12. All others less than 100

12:40 Close (too bad, 0.6" on guider)
