  1. 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

  2. W/ or W/O suppressed cells CTF Meeting 10/7/02

  3. sigma setting VS sigma saw in MC Bin Size Diff in Eta CTF Meeting 10/7/02

  4. 2. MC noise VS noise in data Stat. Of MC CTF Meeting 10/7/02

  5. Difference of MC and data noises CTF Meeting 10/7/02
