Standard Star Fields for March 2007

Prepared by Ed Olszewski, David Sand, and Jill Bechtold - 2007 March 12

This is the list of photometric standard fields for the beginning, middle, and end of the night. Airmass tables are attached at the bottom of this page.

The fields were chosen from http://www.noao.edu/wiyn/obsprog/images/tableA.html

To be decently placed at each twilight plus midnight, fields with a number of Stetson extension observations (see http://cadcwww.dao.nrc.ca/standards/ and click on stetson) to give plentiful BVRI measurements. U band only comes from the original Landolt lists. Only SA97 has no semi-infinite number of stetson standards.

The OBs are in the 1STDOBs/MarchStds/ directory in the sdtobs account. A reasonable estimate is that the 11 exposures per OB, plus slew and primary mirror figure tweakup will require around 12-15 minutes to execute (YMMV).
