Hadrons from fragmentation are sometimes off-shell

[Frank Siegert]

Hadrons from fragmentation are supposed to be on-shell and then be mass-smeared by the decay module. In about 5% of events I get a hadron from fragmentation which is off-shell. This is fortunately not a big problem in the way that the decays are set up at the moment, but it will become a problem once the changes on the hard decays branch come in.

E.g. in trunk DY events with some custom output:

  daughter b(1)(1235) not onshell: p^2=0.472089 vs. m^2=1.2295
  daughter a(2)(1320) not onshell: p^2=0.444415 vs. m^2=1.3181
  daughter a(1)(1260) not onshell: p^2=0.475192 vs. m^2=1.23
  daughter f(2)(1270) not onshell: p^2=0.475163 vs. m^2=1.275
  daughter f(2)(1270) not onshell: p^2=0.462808 vs. m^2=1.275
  daughter h(1)(1170) not onshell: p^2=0.480025 vs. m^2=1.17
  daughter h(1)(1170) not onshell: p^2=0.49642 vs. m^2=1.17
  daughter rho(770) not onshell: p^2=0.37233 vs. m^2=0.77
  daughter f(0)(980) not onshell: p^2=0.511633 vs. m^2=0.98
