LUCIFER Technical Observing, prep for Partner Science:
UT 2010 Mar 07

Observer: D.Thompson, M.Pedani
Telescope Operator: W.Wack
Instrument Support: D.Officer
Telescope Support:
SW support: N.Cushing et al. (Tucson)

Summary

  • Lost entire night to fog, wind.
  • Tests initial DD communication from MODS software
  • Mounted and did initial check out of LBC
    • LBCB has a filter wheel that looks to be out of position
  • LUCIFER ROE and MCE not re-powered when brought out of safe mode

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
