The Infrared Astronomical Satellite (IRAS) surveyed the sky at 12, 25, 60, and 100 µm providing an invaluable, unbiassed far-infrared database for the study of regions of active star formation. We obtain the far-infrared luminosity functions of Taurus and Chamaeleon, within which the stellar populations appear to be at a similar evolutionary stage (within statistical errors). We then convert the far-infrared luminosity functions to equivalent bolometric luminosity functions, and find a shortfall in the number of intermediate and high mass objects when we compared to the initial luminosity function for field stars (Miller and Scalo 1979).
