Caption: Fig. 2.

Radial distribution (in units of arcminutes; x‐axis) of the fractional R2 band excess, η, of the four clusters, defined as ﹩\eta =( p_{2}-q_{2}) / q_{2}﹩, where ﹩p_{2}﹩ is observed R2 band flux and ﹩q_{2}﹩ is the expected R2 band flux from the hot ICM. Negative values of ζ indicate that detected emission is below the expected value.
