Night Plan:

  • MODS checkout (highest priority) - 3 hrs 19:07-22:07
    • If closed or conditions prevent MODS checkout first few hours, please execute during the night as soon as conditions permit before LUCI-AO
    • File Location: /home/lbto/Service_Observing/2021B_D_E/MODS/MODS_Checkout_Jan2022 - OBS-N
      • OT: MODS_Checkout_V2.5.6.xml
      • Scripts have been exported, MMS files in /home/lbto/Service_Observing/2021B_D_E/MODS/MODS_Checkout_Jan2022/Masks
    • Verify AGWs working - 0.5-1hr (can start in twilight)
      • AGW CHECKOUT TO BE DONE IN TWILIGHT - Regardless of cooling status of MODS cooling
        • Seeing up to 2" (<1.2" if adjustments need to be made) - thicker clouds - use brighter stars
        • Test preset - guide and collimate
        • Verify hotspot centered - Wiki Link
          • if by-eye is OK - can skip to next step - otherwise need to iterate using above method
        • check MODS1/MODS2 guide probe wrt/rotator center
          • Files needed:
            • agw.ini located on mods1 and mods2 computers in: /home/mods/Config/MODS1 or /home/mods/Config/MODS2
            • after preset to on-axis bright star
              • Stop guiding in GCSGUI
              • Slew to hold 0 (or 360) LDG or RDG via MCSGUI
              • ptincrement 0 (or 1) CA -5
              • setting 'gprobe 0 0' in MODS GUI command (doing this for both MODS)
              • gcsclient readGuideCam left (or right) -e 1000 (throwaway exposure)
              • gcsclient readGuideCam left (or right) -e 90000
              • slew to hold 360 ldg or rdg via MCSGUI

              • Conversion: X+DETSECX Y+DETSECY
              • MODS-1 hotspot is 254, 201
              • MODS-2 hotspot is 267.00, 240.00
                • Y differential can be as much as 40 pixels - known offset that Y will be < Y value from AGW.INI
        • Verify SH spots centered
        • Verify IT 8315 - 0.1hr
          • Active preset to any target is sufficient - can be checked off when doing the SpecStd
    • Verify Rotator ZP w/astrometric masks - 1hr
      • Can be shifted to end of night - once MODS is cooling
      • Requires seeing < 1.2" - clouds - stars are bright - integrate longer if thicker clouds
      • Best to obtain RotZP values for two masks:
        • ID 532732 - mods.4.g04d25ep.mms - visible twilight 00:30
        • ID 590945 - mods.44.StoneE1f.mms - visible 08:30-03:30
        • ID 550828 - mods.50.StoneI1.mms - visible 01:30- twilight
    • Obtain one Spectrophotometric Standard in all configs - 1hr
      • Can be shifted to end of night - once MODS is cooling
      • G191-B2B (+52dec) - twilight-03hr
      • Feige 34 (+43dec) - 21:30hr-twilight

      • Turn off GOpt after restarting AdSec (if ASM needs to be restarted after some failure)
    • OSCO - 0.5hr
      • check new reconstructor for Bin 1
    • Try Bin 3 again - look for double star effect
      • skip optimize gain
      • need to run in intervention mode
      • acquire telemetry
        • Bin 3 brightness star -
          • ramp up gains, adjust tip-tilt as taking data
        • Use a Bin 2 brightnes star - force it to a BIn 3 mag
          • skip checkflux to verify if we get double-star
          • run optimize gain - see if it fails
    • Bin 1 Tests
      • Address the "10 o'clock bite" issue
      • New reconstructor made during twilight (400 modes)
      • Run R=<8 mag star

        • Run as-is subframe
        • Run with ND+FeII filte combo
    • Bin 4 Tests
      • Confirm or reject the elongation we saw previous night
      • Check at least 1 star at faintest end possible - verify brightness limits (Rmag > 17)
      • Use Bin 3 stars (lets say 15.5 < R < 16.5) as Bin 4 -put R=16.51 in the preset and skip checkflux - verify Bin 4 performance with more photons
        • This is often done with borderline cases
      • Verify the "double" star problem is limited to Bin 3
    • Bin 2 Tests
      • Run through 1 star script in full to confirm Bin 2 works
      • "Pretty pic" (STRONGLY requested by ATT) - use pseudo-science targets - run through script completely
