  • Going to try to use a flat using the old reconstructor and take a new intmat, using the old reconstructor.
  • Flat: 20170707_400_00.sav
  • Flat: 01
  • Disturb: 20170706_115845.fits
  • Intmat: Today_074638
  • Big chunk out of bottom, also present in flat, will go back to flat #00
  • Intmat: 074638
  • @ 990Hz!!!!
  • Strange apparent instabilities at the top of the pupil, sometimes, may be overdriving with disturbance and saturating the pyamid?
