Observing Plan and Goals for the Night

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

Notes from the 4pm meeting

Run Manager's Meeting 12/9/2013
-------------------------------
HTD, Klaus, Lyndsay, Alex, Michael, Margaret, Douglas, Robert
Ricardo, A. Kim

Camera and Telescope
--------------------
Telescope and Camera are OK. Ongoing work on the encoder.
Telescope will be on the white spot as usual.

Last Night
----------
Median seeing 1.27" WF and SN data last night.
It was clear last night, but with high humidity.
QC says it was clear.

DESDM
-----
Friday and Saturday's WF data is being processed.
The difference imaging for SN last night is in processing.

WF DQ:
The old (current) WF assessment scripts are not using
transparency yet. The new script is working its way backward
into September. File or results to go to Eric for Survey Strategy
purposes. Ann E. and Robert G. need to mind-meld, too.
More discussion about how (if) to apply it backwards
but that there should be little harm in applying it for
the past week or two. CSV files for now.
Plan is to run it tomorrow on data from Friday night
and forward.

SN DQ:
There are scripts but it's not clear who turns them, DESDM or SN
Group. Prefer DESDM. Thought that was the plan. Try to get
them plugged-into tomorrow's meeting.

Tonight
-------
Weather is clear. One condor. Moon at the start of the night.
We have C3, X1, X3 at deadman. After that WF.
