ADC_Keywords: Clusters, galaxy ; Redshifts ; Morphology Keywords: galaxies: clusters: individual (Cl 1358+62) - galaxies: evolution - galaxies: structure Abstract: We describe the morphological composition of a sample of 518 galaxies in the field of Cl 1358+62 at z=0.33, drawn from a large Hubble Space Telescope mosaic covering 53 square arcminutes. The sample is complete to I=22, corresponding to MV=-18.5 in the rest frame. The galaxy morphologies have been independently classified by the authors of this paper and by Alan Dressler. Dressler's classifications place our work in context with the previous MORPHS study and allow us to estimate the scatter between different sets of visual classifications. We restrict most of our analysis to the brighter part of the sample, I<21 (MV←19.5), where the scatter between the two sets of classifications is 1 in morphological type.

Note (1): Each pixel for the X and Y positions corresponds to 0.1", and the cluster center is taken to be coincident with the center of galaxy 810 at 2801.93, 2719.27. This corresponds to 13:58:20.7+62:45:33 (B1950.0). Note (2): We consider those galaxies with 94318<cz<102532 to be cluster members. Note (3): DF/MF/PvD classification -5/9; 15; 99; 999: -5 (elliptical), -4 (elliptical or S0), -2 (S0), 0 (S0 or Sa), 1 (Sa), 3 (Sb), 5 (Sc), 7 (Sd), 9 (Sm), 10 (Im), and 99 (peculiar or merger). Intermediate types (2, 4, 6, and 8) were also assigned, with type 15 for intermediate late types. Note (4): AD classification: Following the completion of the DF/MF/PvD classifications, AD independently classified the Cl 358+62 galaxies according to techniques described in Smail et al. (1997ApJS..110..213S). AD does not assign galaxies to the DF/MF/PvD intermediate types -4 (E or S0) or 0 (S0 or Sa) in the same fashion, preferring to subdivide these into E/S0 (-4), S0/E (-3), S0/Sa (-1), and Sa/S0 (0). When discussing the cluster population in broad terms, AD's types -5 and -4 are combined into E, types -3, -2, and -1 into S0, and etc. DF/MF/PvD split the contents of the -4 bin equally into E and S0, and the 0 bin equally into S0 and Sa. When converting AD's descriptive types into numerical types, we have placed a few galaxies into the merger (99) bin where an individual catalog object corresponds to an interacting or merging pair of objects.
