Example fits of projected galaxy number density profiles and line-of-sight velocity dispersion profiles. The cluster shown here is A0085. The galaxy surface number density profile is fit with three Plummer spheres, which are then used as input in the projected Jeans equation. The line-of-sight velocity dispersion profile is used to determine the total mass profile, parameterized using the cNFWt profile with six parameters. Dark and light shadow regions show the 1σ and 2σ confidence intervals, respectively.
