Abstract

The noise-limited magnitudes for the Air Force Geophysical Laboratory (AFGL) Infrared Sky Survey have been estimated by direct comparison with ground-based observations. Using these limiting magnitudes, 'pruned' versions of the AFGL catalog have been generated. Infrared observations of all the stellar objects seen at 11, 20, or 27 microns and a statistical sample of the stars seen only at 4 microns are reported. Analysis of the observations leads to estimates of the absolute 4 and 10 microns magnitudes and space densities for the two clases of objects. The expected results from the Infrared Astronomical Satellite are reexamined.
