Improved Reprocessing of the IRAS Survey (IRIS)
This page gives you access to the Improved Reprocessing of the IRAS Survey (IRIS) collection.
IRIS provides reprocessed 12, 25, 60 and 100 micron images taken by the Infrared Astronomical Satellite (IRAS) over 10 months in 1983. Most light observed at these wavelengths is thermal emission from interstellar dust at temperatures of several 10s of Kelvins, as well as some warmer dust in the vicinity of young stars. These data products represent a major improvement over the latest versions provided by the IRAS team (the ISSA team) in terms of minimized striping and superior calibration. Large-scale information, including the absolute calibration, are obtained from observations by the Diffuse Infrared Background Experiment (DIRBE) and observations by the COsmic Background Explorer (COBE). Unlike an earlier, similar combination of IRAS and DIRBE data by Schlegel et al. (1998), IRIS retains the native IRAS resolution, with superior small-scale and point-source calibration (particularly at 100 microns).
