Infrared survey measurements obtained from two probeborne experiments flown in 1982 combined with extensive ground-based observations on AFGL sources are incorporated into a revised AFGL Four Color Infrared Survey catalog. Over 92 percent of the sky has been covered at 11 and 20 micron, 71 percent at 4 micron and 47 percent at high sensitivity at 27 micron. There are 2970 entries in the main catalog, most of which are multicolor observations. The catalog contents are resolved into two general groups a disk population slope 0.4 with means colors m 11-m202.0 and m20-m270.9 corresponding to color temperatures of 270K and 185K, respectively, and a spherical distribution slope 0.6 with a mean color difference of m11-m201.0 corresponding to T sub c approx 10 480K.
