  * - Mike Lisa March 2018
+ *
+ * ================================================
+ * Update March 2023 (More than 5 years later.  Not bad.)  Mike Lisa
+ * - We now have the DAQ upgrade and DEP readout on the West side.
+ *   DEP information will *always* be there.  QT only at low rate.
+ *   So, now have to store DEP information.
+ *
+ * It means several new methods, and two new data members:
+ * 1) unsigned short DEPdata
+ * 2) float nMIP_DEP
+ * So, now the size of one StMuEpdHit is 16 bytes
