Abstract:
We present a description of deep radio, optical, and near-IR
observations taken with the VLA, the KPNO 2m telescope, and the KPNO
4m telescope of the region containing the rich cluster of galaxies
Abell 2125. The reduction of each data set is described. A catalog of
radio sources apparently not associated with members of A2125 and the
associated R-band magnitudes is presented.
Description:
Observations were made with the VLA for 3.5hr in the 1997 B
configuration and for 27.5hr in the 1998 A configuration. The data
were all taken in spectral line mode 4, which provides seven 3.125MHz
channels in each of two intermediate frequencies (IFs; centered at
1365 and 1435MHz) and each of two polarizations.

Note (1): The first two digits are the facet number and the last three a
sequence number.
Note (2): Where the center is RA=15:41:14.00 and DE=66:15:00.0.
Note (3): If a two dimensional Gaussian was the best fit, we give the major
and minor axis size (FWHM) and the position angle. Upper limits are
given for sources which were unresolved. Sources with sizes only
were estimated directly from the maps using the AIPS task, TVSTAT.
Note (4): Optical/NIR identification status, defined as follows:
i = identifications in at least one of the 10 observed bands;
b = a blank field;
c = an optical field which is too confused to be sure of the identification.
