Notes. Models and associated baryonic mass (first and second columns), and estimated total mass using χ2 probabilities for Einasto, NFW, and gNFW DM density profiles (third to eighth columns, all masses are given in units of 1011 M⊙). The total mass and mass ranges are evaluated using the minimum χ2 (best fit, Cols. 3 and 5) and by weighting the total masses by their χ2 probabilities (average, Cols. 4 and 6), together with associated 1σ uncertainties. Uncertainties also account for systematics related to the Galactic distance and its motion, as well as to change in scale length (∼4% on masses, see Sect. 2.1), which have been added to the quoted error bars in this table.
