Observing Plan and Goals for the Night

  1. Afternoon calibrations - script to use: prenight_calibration.json
  2. Dark frames (20 x 100)
  3. Zeropoint check - preceed with zeros script: flush_Vsub.json
  4. Start of night standards (scripts listed below)
  5. Try to get ObsTac to schedule X3
  6. Nightly out of focus image (right after last standard, no break) - script to use: defocus_nightly.json
  7. ObsTac
  8. Middle of night standard (scripts listed below)
  9. End of night calibrations - if good afternoon calibrations use postnight_calibration.json, otherwise use postnight_zeros_flats.json
