Query: Dwarf Irregular Galaxy Leo A. Suprime-Cam Wide-Field Stellar Photometry   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 ($20' \times
24'$) 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.
