Night Plan

• Test Preset (closed dome)
• Test Preset (open)
• Restart GCS
• AGW 5/6 Checkout
  • Select pointing and collimation stars overhead from pointing tool, use the collimation star
  • Overview of AGW procedure
  • verify SH spots illuminated (0.5 hr)
  • verify hotspot center (1 hr)
• Observe a standard star in all modes (30-45 min for 3 images). If clear, obtain the full set of 3 images per mode; if not, make a note in the object name and obtain only 1 image per mode.
  • BD+33 2642 15h52+32d56 - at start of night (until 10pm)
  • Feige 110 23h20-05d09 - 10:30pm-morning twilight
• Dice-5 imaging offsets
  • Test Science OB
    • Sidereal
    • Non-Sidereal

Issues:

• Data is not being propagated to /Repository on the mountain.
• No Repository directory created for 20200822 in Tucson ( last directory is 20200721)
• Neon lamp appears to be back on for MODS-1 - blinking MODS1 and MODS2 exposures (shifted) shows no difference
  • Red Grating only M1R - Neon lamp on (mods1r.20200822.0119.fits)
• MODS2-Blue sequencer Issue (IT 6386) - 1st two images of night
• New MODS Library
  • Dual Grating M1R took 4 instead of 3 QTH1 flats for the 1.2" slitflat
  • Blue slitless flats M2B - UG5 + Vflat6 = counts 41-42k at the right end of frame (exposure time 1.5seconds) - mods2b.20200822.0118--0122 - MODS1B blue slitless <39k counts w/2sec exptime
  • MODS2B - 2.4" slit Blue-only flat - QTH1 @6 - 3 seconds - counts at extreme right edge are ~45k

PROPOSED PLAN OF ACTION:

• Telescope Wake-up ~0.5hr
  • test presets (sidereal and NS)
• Test SX AdSec out of the beam with LBC-Blue in the beam
• LBC Wake-up - contingent on release of LBC-Blue
  
  • Collimation - DoHybrid, then DOFPIA (~1hr)
  • Superfocus Sequence, PA=0, 180 (1hr)
  • Rotator Center Checks (pairs of 0,180; 90, 270) ~0.5hr
  • Test Science OB ~ 1hr
    • Sidereal
    • Non-Sidereal
  • Photometric Fields and Spectrophotometric Stars (to establish ZPs) ~ 1-1.5hrs
    • Requires multiple airmass visits (clear conditions, any seeing)
    • Cycle through all filters
    • This is now a high priority because we need to define ZPs
  • Twilight Flats
• MODS - contingent on passing functional checkout
  
  • Basic Checkout
    • Verify collimation
    • Verify AGW 5/6 Hotspots are centered
    • Observe a standard star in all modes (30-45 min for 3 images). If clear, obtain the full set of 3 images per mode; if not, make a note in the object name and obtain only 1 image per mode.
    • Dice-5 imaging offsets
  • Test Science OB
    • Sidereal
    • Non-Sidereal

Closed Dome Activities

• MODS Calibrations - using new MODS OT library
  
  • Imaging Flats
    • Dual
    • Red
    • Blue
  • Spectroscopy
    • Dual
    • Red
    • Blue
  • Bias frames
    • check new 2x1 and 2x2 bias from updated MODS library
    • 1x1 Binned Biases
