Detailed Description

Hit data structure.

N.B. The size of this data structure (i.e. the value obtained with the sizeof() operator should exactly match the preset number of bytes from the DAQ system. The pragma statement is necessary to ensure the correct size of this object. Furthermore, this data structure should have no virtual methods and no virtual destructor. Consequently, the standard ROOT CLassDef() macro is replaced by the designated ClassDefNV() macro.
