IRAS Infrared Maps

The first file listed for each map contains HEALPix format data stored in a binary table extension. For the convenience of users who do not require the capabilities that HEALPix offers, we also provide maps in two projected image formats: Mollweide and Zenith Equal Area (ZEA). These files contain the string "_mollweide" and "_zea" respectively, and may be displayed with standard astronomical display software such as DS9 and SAOImage.

Recommended download procedure for files:
right click on the file name and save.
