pppmp0_Tree ChiSq_KinFit MAX BeamPhoton__P4_Measured TargetProton__Mass 4 PiPlus__P4_Measured PiMinus__P4_Measured Photon1__P4_Measured Photon2__P4_Measured ====================== Details: The code doesn't support comments at this moment. And the input parameters have to be listed using the exact order without any empty lines: Line 1: name of the ROOT tree; Line 2: formula to evaluate the best combo from the save event to save, either with maximum or minimum values Line 3: branch for beam particle Line 4: branch for target particle Line 5: number of reconstructed particles Line 6 and so on: branches of reconstructed particles
