00:50 David authorize PFU on both sides. Set the M3 positions to
  • SX Tip/Tilt -1000 -600
  • DX Tip/Tilt-575 -150

01:53 Took an hour to find both stars. They were way off and had to perform two large spiral searches.

02:00 David send preset with new IE and CA's for both sides. Plus, M3's moved back to the config value rather than to the value manually requested.

02:03 Doug change OSS config file, positions.conf, to have new PFU values.

02:08 David send preset with new IE and CA's for both sides. IIF reports co-pointing limit on left and right. David cleared a bunch of stuff and preset was successful, but no stars. IE and CA were not correct. David put in new IE, CA values and resend preset

There were a number of confusing active optics problems after that. Why did active optics work in December, but not now? What caused guiding to spiral around? See the discussion in Issue 4993.

03:50:40 look for SX jump on DX async preset
Was it really an async preset?

3.92 UT SX M1 hits +Z limit after Ilya sends a StepFocus to M1M2
