Left: Ratio of the number of selected clusters after each applied selection with respect to basic cluster selections (see \Tab{tab:clusterbasiccuts}) as a function of the cluster momentum. The green markers indicate the use of the CPV requirement, while the red markers include the CPV and $\shshlo$ selection criteria. For each step, the data are represented by the points, while the lines indicate the same selection step in the simulations. Right: Inclusive photon purity $P$ and reconstruction efficiency $\epsilon_{\gamma}$ as defined in \Eqs{eq:photonPurity}{eq:photonEffi} after applying each cluster selection criterion. Both figures are done using V2 clusters as inputs.
