Notes. The first column labels the models in order of their appearance in Sect. 4.2 of Johnson et al. (2009), where J1: X-ray data, total mass; J2: X-ray data, stars subtracted; J3: X-ray profile including metal abundance gradient, stars subtracted. Columns 2 and 3 are the parameters quoted by these authors, Col. 4 gives R₂₀₀ in units of kpc. The corresponding values for the density ϱ_s and M₂₀₀, i.e. the enclosed mass at R₂₀₀ are given in Cols. 5 and 6.
