ISSA Data Collection Atlas
The IRAS Sky Survey Atlas (ISSA) is a survey of 98% of the
sky in four bands with effective wavelengths of 12, 25, 60 and 100 µm,
which was done during a ten month period from January to November, 1983. The
ISSA covers the sky with 430 fields. Each field is a 12.5° × 12.5°
region centered every 10° along declination bands which are spaced 10° apart.
If you are looking for the 'ISSA Image Server and Catalog Overlays' service,
it can be found here
That service provides single images from the IRAS Sky Survey Atlas, overlaid with
Point Source and Faint Source Catalog information. This Atlas serves multiple ISSA
fits images, covering a large area. Also available are ISSA image "cutouts
using IRSA's Cutouts Service
, which is a
general tool to create single or multiple small FITS (and JPEG) image cutouts of
datasets archived at IRSA.
ISSA images are represented as overlays in red on the
ISSA all-sky composite image above. Either 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.
