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.

  63- 64  I2     mag     mvis     ? Estimated total apparent magnitude

  71- 72  I2     ---     Eps      ? Estimated ellipticity (2)

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