DUSTiNGS Catalog Definitions

Overview

DUSTiNGS consists of a sample of 50 dwarf galaxies 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.

If you use DUSTiNGS data, please cite Boyer et al. (2015).
