This survey, which has the largest areal coverage since the original variable star survey by Baade & Swope (1961AJ.....66..300B), includes photometry for 270 RR Lyrae (RRL) stars, 9 anomalous Cepheids (ACs), 2 eclipsing binaries, and 12 slow, irregular red variables, as well as 30 background QSOs. Twenty-six probable double-mode RRL stars were identified. Observed parameters, including mean V and I magnitudes, V amplitudes, and periods, have been derived. Description: Our survey of the Draco dSph galaxy was conducted at two telescopes: the 1.0m at the US Naval Observatory (USNO) in Flagstaff, AZ, and the 2.3m telescope at the Wyoming Infrared Observatory (WIRO), at Mt. Jelm, Wyoming. Combined, the two data sets cover a time interval of four years (1993-1996). File Summary:
