Far-infrared Column Density and Temperature Data
Far-infrared continuum maps provide an excellent tracer of the warm (~20 K) regions in star-forming regions. The emission is due to a combination of thermally radiating dust and transiently heated dust. Because the emission is usually optically thin, it traces material the entire line of sight and allows for a (temperature weighted) measure of the colmn density. The column density and temperature maps presented here are derived from the latest release of the IRAS data set (IRIS). A description of the method used to derive the dust temperature and column density from the 60 and 100 micron IRAS emission maps can be found in Schnee, Ridge, Goodman and Li (2005).
