Fig. 1

Matter mass M vs. radius R for three profiles. 1) NFW mass profile of Eq. (14): – dashed line; 2) Hernquist profile of Eq. (17):
– thin line; 3) New mass profile of Eq. (19):
– thick line. Here R is in Mpc and M is in 1015 M⊙. The values of the matter mass at radii R = 1.4,4.8,14 Mpc are also shown as given by Eqs. (9)–(11) with 1σ error bars.
