Dwarf irregular galaxy Leo A. II. R and Ha obs.
Listed in IVOA Registry (Virtual Observatory)
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.
Description
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.
