Abstract

We have surveyed the complete extent of Leo A, which is an apparently isolated Local Group dwarf irregular galaxy, in B, V, R, I (the Johnson-Cousins system), and NA656 (centered on H{alpha}) passbands with the Subaru Telescope equipped with the Suprime-Cam mosaic camera. B, V, and I photometry results were published earlier by Stonkute+ (2014, J/ApJS/214/19). The recently published Stetson's high-quality photometric standards in the R passband encouraged us to calibrate and make available to the community deep (R~25mag) R and NA656 photometry results in the field of Leo A (20'x24'). We present the photometry catalog of 28,224 objects in R and 25,800 objects in NA656 passbands. This catalog could serve for future imaging and spectroscopic observation programs of Leo A, especially targeted to study emission-line objects. Also, we demonstrate the capability of the B, V, R, and NA656 passband system to separate Milky Way M-type dwarfs and late-type evolved stars in external galaxies, as well as to recognize early-type (Be, B[e]) emission-line stars.
