Faint Source Model
Mission
COBE/DIRBE

Description

The Faint Source Model gives the predicted contribution to the diffuse sky brightness at 1.25, 2.2, 3.5, 4.9, 12 and 25 microns due to (faint) stars and other discrete Galactic sources. It was used in the search for the cosmic infrared background to subtract an important component of the observed near-infrared sky brightness. The model is described by Arendt et al. (1998, ApJ, submitted) and in Appendix F of the DIRBE Explanatory Supplement. The Faint Source Model files are on line.
