Description:
We present a catalog of point-like sources around NGC 1316, which
forms the photometric database for our paper. This catalogue basically
is a selection from a larger photometric database. The selection
criteria are specified in the paper. The catalog contains coordinates,
R magnitudes with uncertainties, C-R colors and their uncertainties as
well as "sharp" and "chi" values from DAOPHOT II. The coordinates are
for identification purposes only. Depending on the position,
deviations of up to 1 arcsec may occur. See the paper for validity
limits of the photometric calibration, particularly for very red
colors.
