Improved Reprocessing of the IRAS Survey
Listed in IVOA Registry (Virtual Observatory)
This new generation of IRAS images, called IRIS, benefits from better zodiacal light subtraction, calibration and zero levels compatible with DIRBE, and better destriping.
Description
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.
