Photometric data for 34 early-type galaxies in the three high-redshift clusters 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 10-meter telescopes by Oke , Postman & Lubin , are analyzed to obtain the photometric parameters of mean surface brightness , magnitudes for the growth curves , and angular radii at various Petrosian \eta radii . The angular radii at \eta = 1.3 mag for the program galaxies are all larger than 0 \farcs 24 . All of the galaxies are well resolved at this angular size using HST whose point-spread function is 0 \farcs 05 , half width at half maximum . The data for each of the program galaxies are listed at \eta = 1.0 , 1.3 , 1.5 , 1.7 , and 2.0 mag . They are corrected by color equations and K terms for the effects of redshift to the 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 which have been fitted to the observed broad-band ( BVRI ) AB magnitudes of each program galaxy . The listed photometric data are independent of all cosmological parameters . They are the source data for the Tolman surface brightness test made in Paper IV .
