Abstract:
We discuss H-band (1.65{mu}m) near-infrared photometry of the central
9h^-2^Mpc^2^ of Abell 1644 (A1644) to a limiting M_H_~M*_H_+3
(throughout this paper H_0_=100h*km/s/Mpc). here are 861 galaxies in
the photometric survey region. We also measured radial velocities of
155 galaxies; 141 of these are cluster members within 2.44h^-1^Mpc of
the cluster center.
