  1. Notes from 4pm Meeting

Run Manager's Meeting 11/18/2013
Tom, Eric, Marisa, Michael, Margaret, Robert, Arnau, Manuel, Josh

Telescope and Camera status
Telescope is OK. Some work on the dome floor moving stuff around.
Can move for calibrations in about 25 minutes.

Review of previous night¹s data
Some clouds early on.
About 2 1/2 hrs of good y-band data after 2 AM local.
sn deep field in z-band at about 3 UTC seemed saturated with background
from the comfort display. That was C1.

3 small issues annoying the shifters
shutter failures - 2 kinds. The images stuck blades don't get built. The ones with timing
problems do and are reported in the night summary.
stuck guis -
missing backplanes 1,5 -

Feedback from weekend engineering
was executed.

Data Management
Assessments for 11/2, 11/13 are finished and sent to CTIO.
Margaret is looking at the next few nights.

Declaration of SN exposures as bad need to get Steve to look at the data
from yesterday. Steve's report from shortly after the meeting is that the
clouds hadn't kicked-in at the time of the SN C1 exposures.
But 255510 to 255512, X3 z-band, are found as "bad".

Because X3 the z-band didn't finish, Obstac will interpret this
as something that still needs to be done.

There is progress from Marisa on the SN DQ. She has code that
does s/n for fake SN objects and also uses the FWHM info as well.
We think this is being implemented into the big gears of DESDM
data processing.

Nightly observing plan
Kinda cloudy at this time, and we are one day after a full moon.

The current observing plan for tonight can be found here:

Obstac is predicted to do WF Y-band, maybe some z-band. Also some SNs.
