Observing Plan

  • Closed dome SW tests, if requested

  • Twilight flats in NB, BB filters

  • 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

  • Gather NB illumination correction data

  • 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.)
