Get the measured average CMS energy.
Double32_t m_massSpread
Width of the distribution of the center-of-mass energy / invariant mass of the colliding beams.
Abstract base class for different kinds of events.
double getMassSpread() const
Get the spread of the measured CMS energy.
This class contains the measured average center-of-mass energy, which is equal to the invariant mass ...
ClassDef(CollisionInvariantMass, 1)
Measured average invariant mass of the colliding beams and its uncertainty.
Double32_t m_mass
Average center-of-mass energy = invariant mass of the colliding beams.
Double32_t m_massError
Uncertainty of the average center-of-mass energy / invariant mass of the colliding beams.
bool operator==(const CollisionInvariantMass &other) const
equality operator
double getMassError() const
Get the uncertainty of the measured average CMS energy.
void setMass(double mass, double error, double spread)
Set the CMS energy and its uncertainty.
