class PCross: public TObject

  Pluto cross section class
  This utility class computes number of participants according to Gosset
  and meson production probabilities for pi0, eta, omega and phi.
  pi0 and eta are averages of C+C and Ca+Ca TAPS (and KaoS) data,
  omega and phi are mt-scaled from the eta averages.
