35 void setMass(
double mass,
double error,
double spread)
This class contains the measured average center-of-mass energy, which is equal to the invariant mass ...
Double32_t m_massSpread
Width of the distribution of the center-of-mass energy / invariant mass of the colliding beams.
Double32_t m_mass
Average center-of-mass energy = invariant mass of the colliding beams.
