Dust in Nearby Galaxies with Spitzer (DUSTiNGS)
DUSTiNGS consists of a sample of 50 dwarf galaxies within 1.5 Mpc, which have been mapped with IRAC channels 1 and 2 (3.6 and 4.5 microns).
The sample consists of 37 dwarf spheroidal, 8 dwarf irregular, and 5 transition-type galaxies.
The DUSTiNGS data release includes images and source catalogs based on uniform Spitzer
3.6 and 4.5 micron observations. The catalogs are available in "full" and "good" versions, where quality
cuts based on photometric accuracy and source morphology have been applied to the latter.
