Projected mass density profiles (empty markers) for the six convergence maps for the 0306 cluster in the snapshot 101 (z = 0.817). The orange and purple profiles show the fit with NFW and Einasto models, respectively. We give the mean profiles with 1σ contours. From left to right and top to bottom we present the 0, 1, and 2 random projections and 0_pr_axes, 1_pr_axes, and 2_pr_axes principal moment of intertia projections. The vertical cyan line shows the true R₅₀₀ of the cluster.
