Comparison between β(r) profiles from the two methods of the whole cluster member population. In the left panel, we plot all the MAMPOSSt outcomes with an NFW total mass profile, as well as both the JI results (NFW and Hernquist) for reference. In the right panel, similarly, we plot all the MAMPOSSt outcomes with a Hernquist total mass profile. The vertical black line represents the R_200c of the stacked cluster.
