Abstract:
We present a detailed analysis of the photometric properties of
galaxies in the cluster A2163B at redshift z∼0.2 . R-, I- and K-band
structural parameters, (half light radius Re, mean surface brightness
<µ>e within Re and Sersic index n) are derived for N∼60 galaxies,
and are used to study their internal colour gradients.
Description:
The data relevant for the present study were collected at the ESO New
Technology Telescope and include BVRIK photometry centered on the
cluster of galaxies A2163B. During three nights on August and
September 2000, we obtained K-band imaging with the SOFI instrument,
and we also obtained V-, R-, and I-band photometry with the EMMI
instrument. On April 2002, the field A2163B was re-observed in B, V, R
and I band with EMMI.
The table contains the BVRIK photometric catalogue for a sample of
N=131 galaxies in the cluster A2163B at redshift z=0.2. It includes
photometric redshifts, positions, total magnitudes, colours and
structural parameters in the R-, I- and K- bands.
