Too big to be real? No depleted core in Holm 15A
  Partially depleted cores, as measured by core-Sersic model "break radii", are
typically tens to a few hundred parsecs in size. Here we investigate the
unusually large (cusp radius of 4.57 kpc) depleted core recently reported for
Holm 15A, the brightest cluster galaxy of Abell 85. We model the 1D light
profile, and also the 2D image (using GALFIT-CORSAIR, a tool for fitting the
core-Sersic model in 2D). We find good agreement between the 1D and 2D
analyses, with minor discrepancies attributable to intrinsic ellipticity
gradients. We show that a simple Sersic profile (with a low index n and no
depleted core) plus the known outer exponential "halo" provide a good
description of the stellar distribution. We caution that while almost every
galaxy light profile will have a radius where the negative logarithmic slope of
the intensity profile equals 0.5, this alone does not imply the presence of a
partially depleted core within this radius.
