The Araucaria Project: Deep Near-infrared Photometric Maps of Local and Sculptor Group Galaxies. I. Carina, Fornax, and Sculptor

Deep near-infrared $J$- and $K$-band photometry of three Local Group dwarf spheroidal galaxies: Fornax, Carina, Sculptor, is made available for the community. Until now, these data have only been used by Araucaria Project to determine distances using tip red giant RR Lyrae stars. Now, we present entire collection in a form database, consisting accurate magnitudes, sky coordinates, ellipticity measurements, timestamps observations, complemented stars' loci their reference images. Depth our reaches about 22 mag at 5$\sigma$ level, comparable NIR surveys, like UKIRT Infrared Sky Survey (UKIDSS) or VISTA Hemisphere (VHS). Small overlap with VHS no UKIDSS makes database unique source quality photometry.
