  • Things to keep in mind:
    • Watch for opportunity to do ptc scan. "Opportunity"= dome closed at night.
    • defocus_nightly.json is suppose to be run weekly- when are we running next?
      • According to Aaron, photometric conditions aren't important, but seeing should be below 1.2-1.3"

Notes from the 4PM Meeting

  • SISPI GUI starts running 5 minutes behind starting at 10:20 or 10:22UT. Gui commands are instant, but GUI report is stalled.

Other Notes

  • Are there data to declare bad?

Yes, the apply_data_gui shows ~30 main survey observations to
declare bad- these are from nights earlier in the run. It seems
processing is catching up.
