Ratio of different mass profile determinations. Top panels: ratio of the median NFW mass profile determined with MAMPOSSt, M_NFW(r), based on projected phase-space information, to the mass profile determined by direct application of the Jeans equation using full phase-space information, M_Jeans. The red, blue and green symbols refer to the C, C100, and RM samples, respectively. The solid line represents the result for the RM sample obtained by adopting r₂₀₀ as the maximum integration distance in MAMPOSSt. Bottom panels: ratio of M_NFW(r) to the true mass profile, M_true. Left, respectively right, panels show the results obtained on the DLB07, respectively GAEA, samples.
