Abstract:
An optical photometric observation with the
Beijing-Arizona-Taipei-Connecticut multicolor system is carried out
for the central region of the nearby cluster of galaxies Abell 2634.
From the 2Kx2K CCD images with 14 filters, which cover a range of
wavelength from 3600 to 10000{AA}, 5572 sources are detected down to
V~20mag in a field of 56'x56' centered on this regular cluster of
galaxies. As a result, we achieved the spectral energy distributions
(SEDs) of all sources detected. There are 178 previously known
galaxies included in our observations, 147 of which have known radial
velocities in the literature. After excluding the foreground and
background galaxies, a sample of 124 known members is formed for an
investigation of the SED properties. The comparison of observed SEDs
of the early-type member galaxies with the template SEDs demonstrates
the accuracy and reliability of our photometric measurements.
