J/A+A/425/797       BVRIK photometry of A2163B galaxies      (La Barbera+, 2004)

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. File Summary:
