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 | |
