17// First implementation of a class
18// to reject tagged electron coming from conversion, pi0 and eta
19// by calculating the e+e- invariant mass
20// of the tagged electron with other tracks
21// after looser cuts for the partner.
22// PostProcess should extract the background yield
23// If running with MC, it can be compared to the expected background yield
