Figure 3.12 – Number density profiles for A1703, A370 and RXJ1347-11 (top to bottom
plots) for early (upper panels, red circles) and late (lower panels, blue hexagrams) type
cluster members further divided into high (solid) and low-luminosity (empty) subsamples
(as in Fig. 3.11). The redder profiles are more centrally concentrated than the bluer
profiles, suggesting the proportion of early- to late-type members is a clear function of
radius but not as much of luminosity, favoring early-types at smaller radius.
