The AKARI Far-infrared All-Sky Survey Maps is produced with the participation of people from the following institutes: University of Tokyo, ISAS/JAXA, Tohoku University, and University of Tsukuba.
The image data in this release are produced based on the AKARI All-Sky Survey with 4 far-infrared bands at N60 (65 um), WIDE-S (90 um), WIDE-L (140 um), and N160 (160 um).
Akari is Japan's first dedicated infrared astronomical satellite (and the
second infrared space mission following IRTS) launched on February 22, 2006.
Akari's primary mission is to carry out the all-sky survey with the best
sensitivity, spatial resolution and the widest wavelengths. The AKARI/FIS Bright
Source Catalogue Version 1.0 provides the positions and fluxes of 427,071 point
sources in the four far-infrared wavelengths centred at 65, 90, 140, and 160 um.
The sensitivity in the 90 um band is about 0.55 Jy. The AKARI/IRC Point Source
Catalogue Version 1.0 provides positions and fluxes of 870,973 sources (844,649
sources in 9um band and 194,551 sources in 18um band) in the Mid-Infrared
wavelengths.
