Cumulative mass distributions (1) using the X-ray hydrostatic method (filled squares), (2) using the caustic method (black solid curve), (3) of the gas mass estimate (black dotted curve), (4) of the stellar mass estimate of the red galaxies (red dash-dotted curve), and (5) of the stellar mass estimate of the blue galaxies (blue dash-dotted-dotted-dotted curve). The dashed curves and error bars denote 1σ intervals. The open star, triangle, diamond, and circle indicate the dynamical mass estimates () using 53, 48, 24 red, and 29 blue cluster members according to the Biviano et al. (2006) method. The open square and cross denote the richness-derived mass estimates ( and ) based on photometric data using the definitions of Johnston et al. (2007) and Hansen et al. (2009).
