Abstract:
We study the Photometric Plane (PHP), namely the relation between the
effective radius re, the mean surface brightness within that radius
µe and the Sersic index n, in optical (R and I) and near-infrared
(NIR; K) bands for a large sample of early-type galaxies (ETGs) in the
rich cluster MS 1008 at z=0.306.
