Abstract:
    Hubble Space Telescope (HST) imaging of four rich, X-ray-luminous,
    galaxy clusters (0.33<z<0.83) is used to produce quantitative
    morphological measurements for galaxies in their fields. Catalogs of
    these measurements are presented for 1642 galaxies brighter than
    F814W(AB)=23.0. Galaxy luminosity profiles are fitted with three
    models: exponential disk, de Vaucouleurs bulge, and a disk-plus-bulge
    hybrid model. The best fit is selected and produces a quantitative
    assessment of the morphology of each galaxy: the principal parameters
    derived being B/T, the ratio of bulge to total luminosity, the scale
    lengths and half-light radii, axial ratios, position angles, and
    surface brightnesses of each component. Cluster membership is
    determined using a statistical correction for field galaxy
    contamination, and a mass normalization factor (mass within boundaries
    of the observed fields) is derived for each cluster. Morphological
    classes are defined using B/T: disk galaxies have 0≤B/T≤0.4,
    intermediate galaxies 0.4<B/T<0.8, and bulge-dominated galaxies
    have 0.8≤B/T≤1.

Note (1): Identification is the name of the exposure, chip where the
          galaxy was found, x and y pixel coordinates on that chip.
Note (2): The magnitudes are calculated from the best-fit model parameters
          and are thus effectively integrated to infinite radius.
Note (3): Value is 0 for a pure disk galaxy, and 1 for a pure bulge galaxy.

Note (4): The errors are mostly reliable for the single component models,
          and are given in the hybrid model case to indicate the average
          precision of the measurements.
Note (5): Ratio of the length of the minor axis to the major axis of the galaxy.

Note (6): Angle between the major axis of the ellipse and the x pixel
          coordinate axis on the original images.
