ADC_Keywords: Clusters, galaxy; Photometry; Redshifts Keywords: galaxies: clustering-galaxies: distances and redshifts-galaxies: photometry Abstract: We present photometry and spectroscopy for seven deep fields containing distant clusters of galaxies with 0.35<z<0.55. Positions and photometric parameters, including r-magnitudes g-r and r-i colors, surface brightnesses, and photometric profile types are given for about 2000 galaxies. Low-resolution spectroscopy is obtained from which redshifts are determined for 289 objects, of which 190 are cluster members. Description: Photometric observations were made of these clusters using PFUEI and 4-Shooter cameras on the 200 inch Palomar Hale Telescope. Spectroscopic observations were made on roughly 60 nights from 1980 to 1989. Data were taken with the PFUEI at the prime focus and the 4-Shooter at Cassegrain focus. File Summary:

Note (1): Position from a central bright galaxy listed in Table 9 of the paper (aligned to the cardinal directions for all but CL0024+1654, see paper). Note (2): The explanations for columns (4) and (5) in the paper (p47) seem to be different from those in the top of each Table. Note (3): the fitting class is d = de Vaucouleurs, u = unresolved, e = exponential Note (4): Average surface brightness inside the effective radius. The unit is not described in the paper, and is cited from Schneider et al. (1986AJ.....92..523S). Note (5): Caution flag for fit: A = asymmetric C = confused F = too flat S = sky is more than 5 sigma deviant Note (6): details are in the paper, p50. The first letter indicates a member (m) or field (f) galaxy; the following letters give a rough description of the spectrum.
