BLAST 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 second delivery (DR2) of Balloon-borne Large Aperture Submillimeter Telescope (BLAST) data is available here using spatial and visualization tools.
The BLAST data consist of maps at 250, 350, and 500 µm. 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.
Please read the delivery documentation to understand how to interpret the different data products such as 'reduced', 'noise', 'hits', 'decon', and 'decon_noise'. Filter transmission profiles for each observing campaign are available: 2005, 2006.
