LUCIFER Technical Observing, prep for Partner Science:
UT 2010 Mar 08

Observer: D.Thompson
Telescope Operator: W.Wack
Instrument Support: D.Officer
SW support: T.Edgin (on call)

Summary

• Lost entire night to fog, wind, snow.
• Time given to M2 team to diagnose their fiber problem

• LBCR rear cover re-installed.
• LBCB filter wheels checked, seem to be well aligned (just vignetting?).

• LUCIFER Telescope Service restarted, communicates with AO2
• Manual presets and offsets sent from LUCIFER UI, executed as expected
  • GCS triggered once, it did what it should have.

Still to do as of 10:30 MST:

• Enter new mask data into LUCIFER engineering interface

Preparations

Details

Observing Plan

• Closed dome SW tests, if requested
• Expand pointto to include RDG, LDG, RFBG, MODS1
• Correct initial collimation/pointing:
  • Use Brackett Gamma filter, can do in twilight
  • Correct IE/CA at high elevation
  • Correct IA at low elevation (AZ encoder problems)
  • Check/correct IE/CA again at high elevation
• Open dome SW tests, if requested
• Run dice5 pattern to check that things still work
  • Check repeated positioning on LUCIFER with and without flex comp on
• Re-test updatePointingReference functionality.
• Repeat measurement of focal plane scale, orientation
• Check existing collimation model
  • Take new data if necessary
  • Stable conditions!
• Check existing pointing model
  • Implement new collimation model if necessary
  • Stable conditions!
  • Take 12 points, with pointing log on...
  • Take full set (56 points) if the first 12 points are off.
• Collect a "movie" of 2s LUCIFER images while an in-field offset is taking place.
  • Check to make sure offsets still happen in a reasonable manner
• Collect through-focus sequence for Andrew - reasonably dense star field.
  • also check the AGw-LUCIFER focus in cold weather for temp term?
• Collect astrometric field data to check AGw calibration at colder temps
• Improve map of AGw patrol field limits at high field angle
  • Requires set up work on a stone field
  • See this plot for extra patrol field area (in blue): AGw_patrolfield_v2.pdf
• Continue gaining experience with LUCIFER on-sky (e.g. spec acq.)
• March 6-7, End of night - Test of improved MOS acquisition sequence
