/** @class CbmTofDigiExp
 ** @brief Data class for expanded digital TOF information
 ** @brief Data level: TDC CALIB
 ** @version 1.0
 **
 ** The information is encoded into 3*4 bytes (2 Double_t + 1 UInt_t).
 ** Unique Address:                32 bits following CbmTofAddress
 ** Calibrated Time [ps]:          32 bits double
 ** Calibrated Tot  [ps]:          32 bits double
 **
 ** In triggered setup, the time is relative to the trigger time, which 
 ** is measured with a resolution of a few ns corresponding to the TDC 
 ** system clock cycle. 
 ** In free-streaming setups, the time is relative to the last epoch.
