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.
