  2. Data statistics Analyzed periods : 10b, 10c, 10d, 10h, 11a, 11b, 11c, 11d, 11e, 11f, 11h, 12a, 12b, 12c,12d,12e,12f,12g. (very low statistic) 10b, 10c, 11c, 11d, 11f : p-p 7 TeV 10h, 11h: Pb-Pb 2.76 ATeV 11a: p-p 2.76 TeV 12a, 12b , 12c, 12d, 12e, 12f, 12g: p-p 8 TeV What has been studied: • Photon Cluster Charge Distribution and gain (A0) per HV sector • Number of Photons vssin2(qckov) per photocatode. • Number of photons has been normalized for gain. • Number of Pads vs sin2(qckov) per photocatode. (statistics not enough) Tracks selection: • primary tracks selected using standard cuts; • for the number of photons study full accepted rings have been used, applying a cut on the corresponding track position.
