The IRAS Minor Planet Survey (1992) supplements the asteroid data given in the IRAS Asteroid and Comet Survey (1986; catalog <VII/91>); comets are not included in IMPS. All asteroids with reasonably well-known orbits as of December 1990 are covered. In particular, IMPS updates the processing of asteroids numbered 1 through 3318 and extends this processing to asteroid number 4679 plus 2,632 asteroids with preliminary (two or more opposition) orbits. IMPS processed only IRAS survey observations; Low Resolution Spectrometer, Serendipitous, and Additional Observations data were not processed.
