These two clusters, Cl 0023+0423 and Cl 1604+4304, are at redshifts of z=0.84 and z=0.90, respectively. The morphological studies are based on high angular resolution imagery taken with Wide Field Planetary Camera 2 aboard the Hubble Space Telescope. These data are combined with deep, ground-based BVRI photometry and spectra taken with the Keck 10m telescopes. The morphological classifications presented in this paper consist of two parts. First, we provide a quantitative description of the structural properties of ~600 galaxies per cluster field using the Medium Deep Survey automated data reduction and object classification software. This analysis includes the galaxy position, photometry, and best-fit bulge+disk model. Second, for the brightest subsample of ~200 galaxies per cluster field, we provide a more detailed morphological description through a visual classification based on the revised Hubble classification scheme.1998AJ....116..584Lhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/116/584CatalogResearchIsServedByTAP VizieR generic servicerelated-toJ/AJ/116/560 : Cl J0023+0423 and Cl J1604+4304 spectroscopy (Postman+ 1998)J/AJ/122/1125 : BVRI photometry in 3 high-z clusters (Postman+, 2001)http://archive.stsci.edu/mds/mds.cgi : HST Medium Deep Survey WFPC2 cataloghttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/116/584https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/116/584http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/116/584https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/116/584https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/116/584http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/116/584GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapOpticalInfrareddefaultJ/AJ/116/584/table1aCl J0023+0423 field MDS parameters from the automated galaxy classificationsrecnoRecord number assigned by the VizieR team.
