Release of the AKARI-FIS Bright Source Catalogue beta-1.

The AKARI satellite has made an All-Sky Survey at six bands in the mid- and far-infrared spectral region. One of the primary goals of the AKARI survey is to produce all-sky infrared source catalogues. We report the release of the first version of the AKARI FIS Bright Source Catalogue (beta-1) for four of the six wavelengths (65, 90, 140, 160 mu m), containing similar to 63,000 sources. The detection limit of the most sensitive band (90 mu m) is similar to 1.3 Jy, corresponding approximately to a 10 sigma noise level. The photometric accuracy is 30-60%, depending on the band, and the position uncertainty, currently dominated by the FIS data processing, is 4-5 arcsec. The catalogue was prepared for initial scientific validation by the AKARI science team. The revised version will enter the public domain in Autumn 2009. The two other wavelength bands (9 & 18 mu m) data are processed separately for the IRC point source catalogues.
