dc.description.abstractWe present magnitudes and redshifts of galaxies in the cluster of galaxies CL 0017-20 and in the double cluster CL 0500-24. Luminosity functions and velocity distributions have been derived. CL 0017-20 possesses a virial mass of 2.9 x 10(14) M(circle dot) and a V band luminosity of 2.3+/-0.5 x 10(12) L(circle dot) (M/L(V) = 127), much of it in a very compact core of size 113 kpc. Our new velocities and photometry of CL 0500-24 confirm its double nature. Our group algorithm clearly detects two subconcentrations with masses 1.9 and 2.2 x 10(14) M(circle dot). Its total V band luminosity amounts to 2.7+/-0.8 x 10(12) L(circle dot) (M/L(V) of 157). Since the crossing and collapse times in both clusters are smaller than the age of the Universe, they appear bound and virialized. It is surprising that although M/L is small in these clusters, giant arcs have been detected in both.
