Night Plan

• Deploy TCS update after handovoer
• SOUL AO Checkout following problems of 20201220 UT- CRITICAL - 2hours
  • OSCO at handover - 30min - NCPA on / NCPA off
  • AO Scipts: /home/lbto/Service_Observing/D_E_Time_UT_Dec28_Jan_02/AO_Testing/
  • Bin3 Test 0.5-0.75 hr - HIGH priority
    • closed loop data 6 positons of the instrument rotator
    • test the camera lens limits with new M3 position
    • Can use either IDL presets, or AO stars from OT in above directory
  • Bin 1-4 tests on-sky - check functionality
    • use scripts generated from OT in above directory
  • Other Issues:
    • IT 8282 - Bin? pupil files issue
    • IT 8281 - AGW1 loses star at DETXY 10" offset
    • IT 8284 - GOPT issues (pending daytime work too)
    • IT 8271 - preset gains for ESM needed - work on creating the necessary values
  • Observe ESM fields using full AO but with N375 camera - 1 hour per field
    
    • M67
    • HCG 31
  • Additional?
• ESM checkout - (M3 and AO checkout must be completed first) - if not started or completed roll over to another night
  • Scripts: /home/lbto/Service_Observing/D_E_Time_UT_Dec28_Jan_02/ESM_Testing
  • on-sky checks Bin 2 400Hz (FLAO config) vs Bin 2 100Hz (SOUL config) - 1-2 hrs
  • Collect ESM data - <1" seeing - stable - 1hr minmum
    • Palomar 2 - if clear take photometric standards - probing sensitivity vs FLAO - sets at 3am
• MODS Checkout - Medium Priority
  • Verify Rotator ZP with MOS masks (20min)
  • Fields:
    • StoneA - sets 10pm
    • Stone D1f - midnight-2am
    • Stone E1f - midnight-5am
    • Stone I - 3am-twilight
    • MMS files in mms/ sub-directory
  • Collect verification AGW transform (1 hour)
    • Info: https://wiki.lbto.org/Commissioning/ComTools#Guide_Probe_Transformation
• LBC Technical Work - Medium Priority - unlikely to be useful given the HUGE delta-temp for mirrors and ambient
  - O.Kuhn running Technical Work
  • focus offset checks - stable seeing (1" or better on DIMM) - 1.5hr
    • scripts in lbto@robs:~/Service_Observing_D_E_Time_UT_Dec28_Jan02/LBC_R_focus
    • check LBCR R focus, mainly.
      • Focus/collimate, then run superfoc at V+r, followed by a superfoc at [Us,B,g]+R, followed again by superfoc at V+r. Repeat 3x.
  • Gain/Linearity checks - 1hr (photometric conditions, but poor seeing OK)
    • scripts in lbto@robs:~/Service_Observing_D_E_Time_UT_Dec28_Jan02/LBC_Linearity
    • observe a star field with successively longer exposure times, so that a set of stars will have counts that range from 1000 ADU to saturation.
    • several star fields will be chosen, with published photometry (SDSS or other) so we can not only examine the linearity but check the sensitivity.
  • TMS: Run TMS in active mode while collecting a series of pupil images (dfoc = -0.8, Z4/Z11 as sent by fpia) - 2hr any conditions

• Poor Weather Backups
  
  • ESM data collection: this is different than ESM tests above - this is sytematic data colleciton - above is checking on paramters for optimal use
    • Scripts: /home/lbto/Service_Observing/D_E_Time_UT_Dec28_Jan_02/ESM_Testing
    • M67 (3 filters and bright and faint AO Ref star)
    • NGC 3921 all filters
  • ICRF3 Spectroscopy (Rothberg)
    • Scripts: /home/lbto/Service_Observing/Nov_Dec_2020_E_D_Nights/Poor_Weather/ICRF3_Rothberg_2020B
    • ICR5 93.24-13.51 Highest Priority - cycles through G210 K,H,J, and z (fraternal or mono)
      • sets at 3am
      • Target can sustain 2mags of extinction or more - uses 0.25" slit - J=12, H=9.5, K=7.2
    • Observe telluric first
    • Double Check high Dec objects to make sure telluric/science are close spatially
  • If clear but poor seeing, please observe standard stars, cycling through z,J,H,K,Ks
    • Scripts: /home/lbto/Service_Observing/Nov_Dec_2020_E_D_Nights/Poor_Weather/LUCI_Phot_ZP
    • Select stars to use based on visibility - OT file is in directory, export the scripts as needed
    • Please observe the same star at least two times at different airmasses
