Cumulative projected total mass profiles for the nine clusters in the sample. The red dots show the measured values with their corresponding errors (1σ error bars), and the solid lines represent the best fits of the M_SL(R) profiles of each mass model (NFW, NIS, Hernquist, and beta model). The shaded regions represent the 1σ (68%) confidence regions. Each dashed rectangle is zoomed-in the upper left corner of each plot.
