Abstract:
We present images, integrated photometry, and surface-brightness and
color profiles for a total of 1034 nearby galaxies recently observed
by the Galaxy Evolution Explorer (GALEX) satellite in its
far-ultraviolet (FUV; lambdaeff=1516Å) and near-ultraviolet
(NUV; lambdaeff=2267Å) bands. Our catalog of objects is derived
primarily from the GALEX Nearby Galaxies Survey (NGS) supplemented by
galaxies larger than 1' in diameter serendipitously found in these
fields and in other GALEX exposures of similar of greater depth. The
sample analyzed here adequately describes the distribution and full
range of properties (luminosity, color, star formation rate [SFR]) of
galaxies in the local universe.

Note (1): In AB scale corrected for Galactic extinction.

The error in the FUV and NUV zero-point calibration is estimated to be
∼0.15mag in each band.
Note (3): Of the ellipse including half of the total (asymptotic) light of
the galaxy in the FUV/NUV band.
Note (4): We only computed the effective radius and concentration index C31
(C42) for those galaxies whose radii containing 50% and 25% (20%),
respectively, of the light were larger than 6arcsec.

where the profile morphology differs between the FUV and NUV bands two
types are given, separated by a comma with the FUV profile first. See
