Active Optics Tests at LFBG and LDG, 20-21 June 2013 UT

LFBG focal station

  1. DONE Initial pointing, alignment and collimate on-axis
  2. DONE Measure to confirm or correct pupil wobble on SH WFSC (pupil_collect.pro) No Change Needed
    • Change tertiary position if needed
  3. ALERT! Correct binodal astigmatism by analyzing focal plane tilt
    • ALERT! Collect initial field data set (field_collect.pro) /home/dlmiller/data/20130620/initial
    • ALERT! Determine M2 correction from focal plane tip (field_process_set.pro)
      • Iterate till focal plane tilt is near 0
    • ALERT! Collect three sets of data with +-40" tilt and +40 tip
    • ALERT! Collect one set with -40 tip but also collimation at the off-axis position (field_collect.pro with modification)
  4. ALERT! Collect collimation data at various pupil positions relative to sub-ap centers (pupil_shift_collect.pro with modification)

LDG focal station

  1. ALERT! Initial pointing, alignment and collimate on-axis
  2. ALERT! Measure to confirm or correct pupil wobble on SH WFSC (pupil_collect.pro)
    • Note, cannot change pupil wobble if it exits
  3. ALERT! Check binodal astigmatism by analyzing focal plane tilt
    • ALERT! Collect initial field data set (field_collect.pro). Should be near zero because set with LFBG above
    • ALERT! Collect three sets of data with +-40" tilt and +40 tip
    • ALERT! Collect one set with -40 tip but also collimation at the off-axis position (field_collect.pro with modification)
  4. ALERT! Collect collimation data at various vignetting positions (pupil_shift_collect.pro with modification)
