Dynamical mass profiles of six disturbed clusters of galaxies. Solid lines are the hydrostatic mass profiles derived from the surface brightness fits using the β function from Chen et al. (2007). Points with the error bar show the total mass profiles from the line-of-sight velocity dispersion. Vertical dashed lines indicate the positions of r₅₀₀ measured from X-ray data by Zhang et al. (2011), while dotted lines mark R_half enclosing 50% of the total cluster galaxies. 3D radii are chosen according to the binned projected radii to avoid oversampling. That the dynamical mass profiles determined from different tracers are inconsistent presumably indicates nonequilibrium conditions stemming from recent or ongoing mergers.
