h2. Notes from 4PM Meeting 
52 1 Marty Murphy
53 1 Marty Murphy
For tonight:
54 1 Marty Murphy
55 1 Marty Murphy
* OBSTAC
56 1 Marty Murphy
57 1 Marty Murphy
* C1, C2, & C3 reverberation mapping fields at 03:30 UT (00:30 local)
58 1 Marty Murphy
59 1 Marty Murphy
* [if seeing is bad*] do reverberation mapping
60 1 Marty Murphy
61 1 Marty Murphy
*This means if the psf is > 1.6 arcsec for several exposures in a row with no sign of improvement. Choose which script to use based on the SN field that is transiting at the time the seeing is bad. Use http://des-ops.fnal.gov:8080/prednight/ to decide which one.
62 1 Marty Murphy
63 1 Marty Murphy
If poor seeing persists after Reverberation Mapping then Photosweep, then Narrowband (details below):
64 1 Marty Murphy
65 1 Marty Murphy
Photosweep
66 1 Marty Murphy
----------
67 1 Marty Murphy
68 1 Marty Murphy
If you have "Bad Seeing" and photometric and not worse than 2.0", do
69 1 Marty Murphy
Photosweep. Instructions can be found here:
70 1 Marty Murphy
71 1 Marty Murphy
   https://cdcvs.fnal.gov/redmine/projects/desops/wiki/Y6_global_photometry_program
72 1 Marty Murphy
73 1 Marty Murphy
Do not bother with this program if clouds are visible on Rasicam or if
74 1 Marty Murphy
seeing is highly variable, for the varying aperture corrections make
75 1 Marty Murphy
it difficult to get to mmag accuracy.
76 1 Marty Murphy
77 1 Marty Murphy
One needs to run a script at CTIO to generate the jsons (see the
78 1 Marty Murphy
instructions wiki page). Having done that the Photosweep scripts can
79 1 Marty Murphy
be found in
80 1 Marty Murphy
  /usr/remote/user/DECamObserver/ExposureScripts/DES_scripts
81 1 Marty Murphy
with names like: photosweep20180914-2200Z.json
82 1 Marty Murphy
83 1 Marty Murphy
Select the one with timestamp closest to the next top of hour, now in
84 1 Marty Murphy
UT (we got the z added).  Do not bother with this is there's < 30
85 1 Marty Murphy
minutes left in the night.  A script probably takes an hour.
86 1 Marty Murphy
87 1 Marty Murphy
Narrowband
88 1 Marty Murphy
----------
89 1 Marty Murphy
90 1 Marty Murphy
If "Bad Seeing" and not photometric, or if "Bad Seeing" and everything
91 1 Marty Murphy
else if done, then do Narrowband. Instructions and a description can be found here:
92 1 Marty Murphy
93 1 Marty Murphy
   https://cdcvs.fnal.gov/redmine/projects/desops/wiki/Narrowband_SN_imaging_program
94 1 Marty Murphy
95 1 Marty Murphy
Narrowband scripts are in the same directory as Photosweep, and have names like SN-C3X-N964.json
96 1 Marty Murphy
97 1 Marty Murphy
They are on the SN fields, so select the field that is closest to transit. Transit time for SN fields can be found on this page:
98 1 Marty Murphy
99 1 Marty Murphy
   http://des-ops.fnal.gov:8080/prednight/ 
100 1 Marty Murphy
101 1 Marty Murphy
These are expected to be about an hour long. If the clouds are only moderate, we could do these.  Again, Obstac if seeing isn't bad, and waiting on reverb mapping fields to near transit.
