Abstract:
We present the results of a redshift survey of galaxies in the A3528
complex, a chain of interacting clusters in the core of the Shapley
Concentration.
The spectroscopic observations were performed at the 3.6-m ESO
telescope at La Silla, equipped with the OPTOPUS multifibre
spectrograph, on the nights of 1991 March 8-9 (for the Field 10) and
from 1993 February 23-27.
