Abstract:
To separate stars and galaxies in the far infrared AKARI All-Sky
Survey data, we have selected a sample with the complete color
information available in the low extinction regions of the sky and
constructed color-color plots for these data.We looked for the method
to separate stars and galaxies using the color information.
We performed an extensive search for the counterparts of these
selected All-Sky Survey objects in the NED and SIMBAD databases. Among
5176 selected objects, we found 4272 galaxies, 382 other extragalactic
objects, 349 Milky Way stars, 50 other Galactic objects, and 101
sources detected before in various wavelengths but of an unknown
origin. 22 sources were left unidentified. Then, we checked colors of
stars and galaxies in the far-infrared flux-color and color-color
plots.
Description:
The catalog contains names, coordinates, counterparts and far-infrared
fluxes of 5176 sources detected by the AKARI FIS All Sky Survey
(Bright Source Catalogue, version beta-1, Cat. II/298) in the sky
regions with COBE DIRBE 100um sky emission intensivity lower than
10MJy/sr, in all four FIS AKARI bands, i.e. with a complete
far-infrared color information. Sources are associated with the known
galactic and extragalactic objects from the databases: NED (NASA/IPAC
Extragalactic Database) and SIMBAD.

Note (1): As the name of the associated counterpart, in most cases
the primary name given by the NED is used. In some cases, when the
counterpart could be found only in the SIMBAD database and was not
found in the NED (it applied mainly to some Galactic objects), it is
marked by adding "SIM:" before the name. 22 sources for which no
counterpart could be associated are marked as "Not identified".
Note (2): Errors for AKARI fluxes are estimated to be:
35% at 65um (N60 band); 30% at 90um (WIDE-S band), 60% at 140um
(WIDE-L band), and 160% at 160um (N160 band).
