Dwarf Irregular Galaxy Leo A. Suprime-Cam Wide-Field Stellar Photometry

Abstract

We have surveyed a complete extent of Leo A - an apparently isolated gas-rich low-mass dwarf irregular galaxy in the Local Group. The $B$, $V$, and $I$ passband CCD images (typical seeing $\sim$0.8") were obtained with Subaru Telescope equipped with Suprime-Cam mosaic camera. The wide-field ($20^{\prime }\times 24^{\prime }$) photometry catalog of 38,856 objects ($V\sim 16-26$ mag) is presented. This survey is also intended to serve as "a finding chart" for future imaging and spectroscopic observation programs of Leo A.
