Improved Reprocessing of the IRAS Survey (IRIS)
The goal of the new reprocessing was to solve calibration, zero level and striping problems in the IRAS data. The almost all-sky survey has been performed in 4 bands : 12 microns (at 3.8'), 25 microns (at 3.8'), 60 microns (at 4.0') and 100 microns (at 4.3'). Observations were made in three different epochs (HCON1, HCON2 and HCON3). The IRIS NOHOLES files correspond to the original unobserved regions filled with DIRBE.
The brightness maps, as well as uncertainty maps are in MJy/sr
.
