Improved Reprocessing of the IRAS Survey

This new generation of IRAS images, called IRIS, benefits from better zodiacal light subtraction, calibration and zero levels compatible with DIRBE, and better destriping. At 100 microns, the IRIS product is also a significant improvement over the Schlegel et al. (1998) maps. IRIS keeps the full ISSA resolution, includes well calibrated point sources, and the diffuse emission calibration at scales smaller than 1 degree was corrected for the variation of the IRAS detector responsivity with scale and brightness. The uncertainty on the IRIS calibration and zero levels is dominated by the uncertainty of the DIRBE calibration and the accuracy of the zodiacal light model.

This dataset or service is made available by the Infrared Science Archive (IRSA) at IPAC, which is operated by the California Institute of Technology under contract with the National Aeronautics and Space Administration.
