+The fitted MGE profile has 8 Gaussian components. I assumed that I knew the distance (1.862 kpc) and fitted only the mass profile. I used the same set of Gaussians as for the surface brightness profile, but allowed their relative contributions to vary to best fit the underlying mass distribution of the cluster.
