| Description: 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 microns, 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 deg. by 12.5 deg. region centered every 10 deg. along declination bands which are spaced 10 deg. apart. |
