Detailed Description

Represent a single object in a Fourvec_Event, this is just a dumb data container. Each object in a Fourvec_Event has the following attributes:

Four-momenta.
Mass. The kinematic fit assumes a fixed mass for each object, this is specified by the mass attribute.
Uncertainty in momentum .
Uncertainty in azimuthal angle $\phi$ .
Uncertainty in pseudorapidity $\eta$ .
Muon/inverse momentum flag. If the flag is set to true, then the uncertainty is interpreted as uncertainty in instead of .
Label, an integer label that can be used to identify the object type: e.g. lepton, b-jet from hadronic top, etc.
