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 (January to November) in 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.
