IRAS Galaxy Atlas (IGA) Overview
IGA Overview IGA Data Access IGA Cutouts


The IRAS Galaxy Atlas (IGA) is a high resolution image atlas of the Galactic plane at 60 and 100 microns. It has been produced using the IRAS satellite data. The HIRES program was developed by the Infrared Processing and Analysis Center (IPAC) to produce high resolution (~ 1 arcmin) images from IRAS data using the Maximum Correlation Method (H.H. Aumann, J.W. Fowler and M. Melnyk, 1990, Astronomical Journal, 99, 1674). Associated with the IGA Data Atlas are The Extended IRAS Galaxy Atlas (EIGA) and Mid-Infrared Galaxy Atlas (MIGA), which are both servered from IPAC.
