Top panel: average excess surface mass density profile averaging six different projections of the same cluster (halo-4 at z = 0.22): three randoms and three preferentials. For comparison, the solid blue, red, and green curves show the individual profiles around the three random projections, and the dashed blue, orange, and green lines show the cluster oriented along the minor, intermediate, and major axis of the moment of inertia tensor ellipsoid. Bottom panel: relative difference of the individual profiles with respect to the averaged one.
