Abstract
Photometric data for 34 early-type galaxies in the three high-redshift clus ters Cl 1324+3011 (z = 0.76), Cl 1604+4304 (z = 0.90), and Cl 1604+4321 (z = 0.92), observed with the Hubble Space Telescope (HST) and with the Keck 1 0 m telescopes by Oke, Postman, & Lubin, are analyzed to obtain the photome tric parameters of mean surface brightness, magnitudes for the growth curve s, and angular radii at various Petrosian eta radii. The angular radii at e ta = 1.3 mag for the program galaxies are all larger than 0."24. All the ga laxies are well resolved at this angular size using HST, whose point-spread function is 0."05. half-width at half-maximum. The data for each of the pr ogram galaxies are listed at eta = 1.0, 1.3, 1.5, 1.7, and 2.0 mag. They ar e corrected by color equations and K-terms for the effects of redshift to t he rest-frame Cape/Cousins I for Cl 1324+3011 and Cl 1604+4304 and R for Cl 1604+4321. The K-corrections are calculated from synthetic spectral energy distributions derived from evolving stellar population models of Bruzual & Charlot, that have been fitted to the observed broadband (BVRI) AB magnitu des of each program galaxy. The listed photometric data are independent of all cosmological parameters. They are the source data for the Tolman surfac e brightness test made in Paper IV.
