Abstract:
Data are presented from a study of 55 rich clusters of galaxies. The
data include positions, morphological types, estimated total
magnitudes, bulge sizes, and ellipticities for ∼6000 galaxies, as
determined from high scale photographic plates. data reduction
procedures are described, and a brief analysis of cluster richness,
which indicates that Abell richness classes are only rough indicators
of total cluster membership, is included.

Note (1): mV ≃ -19 - mb/2
mb = -1 means no bulge
mb = -2 means indeterminate
Note (2): e = -2 means indeterminate
