χ2 contours describing the agreement between the data and spherical Jeans models of the combined profile with constant mass-to-light ratio M/L = 1.1, the numbers denote the respective value of χ2. Left: β = const., right: β ∝ r. In the case of radially varying anisotropy the abscissa denotes the value of βout, the maximum anisotropy in the outermost part of the cluster.
