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