  44. snarlno=694 University of Athens

  45. More peculiar measurements University of Athens

  46. snarlno=17800: TOF = -1492, Cerenkov=True, muon-like track University of Athens

  47. snarlno=3719: electron-like TOF and Cerenkov, but muon-like tracks University of Athens

  48. In all the preceding event displays, hits with nnpe < 1 were omitted. But where should we put the pulse-height threshold so as to cut the cross-talk and other noise, without cutting the “real” hits? unbiased distribution of all the hits of all the events only hits located at strip<5or strip>20 (marginal) nnpe University of Athens

  49. at this color-scale all red hits are nnpe>2, hence significant hits, whileit is possible to compare the low-pulse-height hits of variant color University of Athens
