The Auriga-California Molecular Cloud (ACMC) Herschel data include PACS (70 and 160 µm) and SPIRE (250, 350, and 500 µm) imaging for the East, Center, and West regions of the cloud. Each image is a 5-extension FITS file containing the Signal Map, Error Map, Total Drifts, Weight Map, and the Signal Map weighted to exclude noisy scans. In addition, each pointing has a temperature and a density map associated with it.
The canonical paper for ACMC is Harvey et al. (2013).
