摘要：

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 similar to 0 ''.8) were obtained with the Subaru Telescope equipped with the Suprime-Cam mosaic camera. The wide-field (20' x24') photometry catalog of 38,856 objects (V similar to 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.
