October-November 1997 WIYN followup priority list version 2.0. ====================================================================== FINAL REFERENCES NEEDED --> Only do this if the seeing is 1.1" or better! These images will be subtracted from every other image of the SNe, so they need to be good. The night does NOT need to be photometric for these images to be useful. Jog multiple exposures by a few tens of arcseconds relative to each other to avoid the chance of getting zapped in every image by a bad spot on the array coincident with the supernova host galaxy. For the 97 SNe, the number of frames we would "ideally" like are listed. One fewer exposure would still be useful. If the seeing is very good (~0.7-0.8" or better), then 3x1000s in R and 3-4x1000s in I should be good enough as a final reference image. Use Harris R, Harris I filters. Prio: 1 is highest, 5 is lowest. Fields which will be available through January are lower priority because it is possible that we will be able to get good references when we request SN followup time then. None of this should be considered as high priority as the observations we will request in January.

They will be useful under any non-extreme seeing condition (i.e. any seeing <= 2" is probably OK). See the standard star fields below for a sample of appropriate Landolt fields. If "final reference fields" for these SNe are observed on a photometric night, standard stars also observed that night will serve the purpose of the calibration, so separate calibration exposures become unnecessary. Priorities are 1 highest, 5 lowest, as with the final reference fields.

There are probably more fields listed than you will want to do, although, of course, with any calibration data, more is better!
