vi) Photon ID/Recovery Use simple cut-based photon ID in the early (CPU intensive)stages of P<strong>and</strong>oraPFA In the final stages, use improved photon ID based on theexpected EM longitudinal profile <strong>for</strong> cluster energy E 0 Convert cluster into energy depositions per radiation length(use cluster to determine the layer spacing, i.e. geometry indep.)Cluster profileExpected Shower Profile fixed by cluster energy But fit <strong>for</strong> best shower start, s Normalise areas to unity <strong>and</strong> calc.s Gives a measure of fractional disagreement in obs/exp profiles Use f <strong>and</strong> s to ID photonsCCAST-Tsinghua School, 26/4/2009 Mark Thomson 31
