Description:
The InfraRed Camera (IRC) onboard AKARI has a comprehensive wavelength
coverage with 9 photometric bands at 2-24 micron. Based on the
NEP-Wide survey of AKARI (which covered a 5.4 sq.deg circular area
centered on the NEP), we constructed a catalog for the infrared
sources found in the survey area. Here we present the catalog
containing about 114,800 sources detected at the nine IRC filter
bands. This is a band-merged catalogue including all of the photometry
results from the supplementary optical data as well as the IRC bands.
To validate a source at a given IRC band, we searched counterparts in
the other bands. The band-merging was done based on this
cross-matching of the sources among the filter bands. If there is no
detection in a certain band, we assigned the 99.000. The NIR sources
having no counterpart in any other bands are finally excluded to avoid
the false objects. See the reference for the details of the NEP-Wide
survey and data reduction.

Note (1): Photometric flags from Sextractor as follows:
1 = the object has neighbors
2 = the object was originally blended with another one
4 = least one pixel of the object is saturated
8 = the object is truncated (close to the image boundary)
Note (2): indicates partially damaged sources during the cosmic-ray
rejection, masking of MUX-bleeding, as follows:
2 = in filter N2
3 = in filter N3
4 = in filter N4
6 = in more than one filter
