MC Noise Study • Neutrino MC, 1000 events (Serban) • Version p11.12.01, new noise file • Small suppression • Grouping: each layer, 2 in |ieta|, all iphi • => 17 * 20 = 340 plots • Compare w/ sigma setting in generation • Compare w/ noise from data • Get RMS from plots (=>suppressed) • Put back suppressed channels • In each event, valid but absent cells • are assumed to have E ~ 1 MeV slightly • Get RMS from “unsuppressed” plots • Take average for sigma of MC • No beam data (1.5 online suppression) 10k • Neutrino MC pass 1.5 offline suppression • Compare RMS CTF Meeting 10/7/02
