Submillimeter continuum maps provide an excellent tracer of both cold and warm regions in star-forming regions. The emission is primarily due to thermally radiating dust and is usually optically thin. The emission, therefore, traces the entire line-of-sight and allows for a (temperature weighted) measure of the column density. The data presented here is taken at the James Clerk Maxwell Telescope using SCUBA.

Update: It has come to our attention that the original COMPLETE 6" pixel SCUBA maps had a calibration error, resulting in the flux per beam being undervalued by a factor of 2. This error has been corrected as of July 9th 2007 and new versions (v3) of the maps are now available through the following pages.

New version (v2) were posted April 11, 2006. This version includes a small fix to the headers which results in a 1/2 - 1 pixel shift in the map. These files have been superseded by version 3 (above).
