The Auriga-California Molecular Cloud: PACS and SPIRE Data Atlas
You can get a close-up map of a region by clicking on any area in red on the above image, or by using the 'Quick Search' links or by typing a coordinate below. The grid overlay above is in Galactic coordinates.
The Auriga-California molecular cloud is a large region of relatively modest star formation that is part of the Gould Belt. The Herschel Space Observatory program OT1_pharvey01_3 ("The Auriga-California Molecular Cloud: A Massive Nearby Cloud With Powerful Diagnostics For Early Stages of Star Formation", PI Paul Harvey) observed a 14.5 square degree area of the cloud in five far-infrared bands. The first delivery (DR1) of the Herschel program is available here using spatial and visualization tools.
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.
ACMC catalog data are available using IRSA's Catalog Search Engine, which allows for complex search queries.
Images are represented in red as overlays on the ISSA all-sky image above. Use the Quick Search below to get data for an entire field, or type in a coordinate or click on any red region to get a close-up of the area; the size of the search is adjustable except when using Quick Search.
The canonical paper for ACMC is Harvey et al. (2013).
