IRAS

IRAS (for Infrared Astronomical Satellite) operated for most of 1983, surveying 250,000 infrared sources at 12, 25, 60, and 100 micrometers. Instruments:

• SA - Survey Array.
• LRS - Low Resolution Spectrograph.
• CPC - Chopped Photometric Channel.

Catalogs produced include:

• IRAS-PSC (sometimes just listed as PSC) - IRAS Point Source Catalog.
• IRAS-FSC (sometimes just listed as FSC) - IRAS Faint Source Catalog.
• IMPS - IRAS Minor Planet Survey, gleaned spectroscopic information on asteroids from existing survey data.
• ISSA - IRAS Sky Survey Atlas - images of sky at four wavelengths.
