Surface brightness profiles of our 16 BCGs ordered by increasing redshift. The filled circles are the data, and the line is the best‐fitting de Vaucouleurs (﹩r^{1/ 4}﹩) profile. The vertical mark in the upper left corner denotes the angular resolution limit (i.e., FWHM of the PSF) of the NICMOS images. All but three of our BCGs are well described by a de Vaucouleurs profile beyond the resolution limit and out to at least ~2 NIC2 ﹩r_{e}﹩. The notable exceptions are MS 0302.5+1717, CL 0016, and 1041+4626. The BCG MS 0302.5+1717 is actually best fitted by a pure exponential disk profile, the BCG CL 0016 has a prominent dust lane, and the BCG 1041+4626 lies at the corner of a frame where the local background varies significantly.
