Surface density profiles for Virgo cluster galaxies. Profiles are measured in circular annuli centered on M87. The left and right panels show profiles found for subsets of the galaxy population after dividing by structural code and star formation code, respectively. The vertical dashed lines show the radii at which the total (i.e., full sample) surface density profile falls to one-half (r50) and one-tenth (r10) of its peak value.
