Abstract:
The Sloan Digital Sky Survey (SDSS, Stoughton et al.,
2002AJ....123..485S 2002AJ....123..485S) has scanned the entire region containing the
Draco dwarf spheroidal galaxy to 23mag in g*. We present a catalog of
stars found in a 453 arcmin2, elliptical region centered on the
Draco dwarf spheroidal galaxy. Objects in the catalog are matched with
five previously published catalogs. The catalog contains SDSS
photometry for 5634 individual objects, and also the photometry from
matches to any of the other catalogs. A comparison of the photometry
between catalogs allows us to identify 142 candidate variable objects.
One hundred and twelve of the suspected variables have colors
consistent with RR Lyrae variables.
Description:
The CCD imaging observations of Draco are taken from SDSS runs 1336
and 1339, which were obtained 2000 April 4 with the SDSS mosaic
imaging camera .
