//   Purpose: HPP file for Calorimeter Channel 
//             Data Definition for Online Calibration 
//             -- Contains mean & sigma for *1 & *8 Gain paths
//                + Null Error code to be set at validation 
//                + event count per channel
//
//   Output : CalCalib_Chn Object
