Comparison between each projected SB profile distribution of a regular (left panel) and irregular (right panel) cluster. The regular cluster maps appear very similar to each other despite the projection, so all the SB profiles that refer to different lines of sight present a similar behavior as well and thus show a narrow distribution. On the other hand, the irregular cluster appears very different depending on the considered projection, so its SB profile presents different shapes, making the profile distribution scatter considerable (depending on the radius).
