Photometric data for 34 early-type galaxies in the three high-redshiftclusters 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 Keck10-meter telescopes by Oke, Postman & Lubin, are analyzed to obtain thephotometric parameters of mean surface brightness, magnitudes for the growthcurves, and angular radii at various Petrosian eta radii. The angular radii ateta = 1.3 mag for the program galaxies are all larger than 0.24". All of thegalaxies are well resolved at this angular size using HST whose point-spreadfunction is 0.05", half width at half maximum. The data for each of the programgalaxies are listed at eta = 1.0, 1.3, 1.5, 1.7, and 2.0 mag. They arecorrected by color equations and K terms for the effects of redshift to therest-frame Cape/Cousins I for Cl 1324+3011 and Cl 1604+4304 and R for Cl1604+4321. The K corrections are calculated from synthetic spectral energydistributions derived from evolving stellar population models of Bruzual &Charlot which have been fitted to the observed broad-band (BVRI) AB magnitudesof each program galaxy. The listed photometric data are independent of allcosmological parameters. They are the source data for the Tolman surfacebrightness test made in Paper IV.Comment: 17 pages, 7 figures; accepted for publication in the Astronomical  Journa
