Mass profiles of the four objects for which Fisher et al. (1995) measured velocity dispersion profiles across the BCG. These profiles consist of an NFW component (blue) to account for the large-scale cluster potential and an isothermal component (red) to account for the stellar components in the inner regions. Agreement is seen both with the enclosed masses at small radii inferred from the observations of Fisher et al. (1995) and at large radii, where the profiles are compared to the M₂₅₀₀ values reported from a variety of sources that employed both X-ray (Vikhlinin et al. 2006; Allen et al. 2008; Main et al. 2015) and weak-lensing (Cypriano et al. 2004; Kubo et al. 2009) methods for mass estimation.
