We study the photometric and structural properties of spectroscopically confirmed members in the two massive X-ray‐selected z ≈ 0.83 galaxy clusters MS 1054‐03 and RX J0152.7‐1357 using three-band mosaic imaging with the Hubble Space TelescopeAdvanced Camera for Surveys. The samples include 105 and 140 members of RX J0152.7‐1357 and MS 1054‐03, respectively, with ACS F775W magnitude i775 < 24.0. We fit the 2-D galaxy light profiles to determine effective radii and Se rsic indices; deviations…
