Each column shows the GALFIT input and output for the 16 cluster ellipticals at z = 1.27: ACS − F850LP band image of the galaxy (upper box), best-fitting Sérsic model profile (middle box) and residual image (lower box) obtained by subtracting the model from the image. Galaxies are (from top left to bottom right): (upper panel) ID. #1, #2, #3, #4, #5 #626 and #657, #606, #590; (lower panel) #568, #719, #1250, #173, #1160, #1471. Each image is 3 × 3 arcsec.
