        Dear Hiro,
                I have to write a hit definition for the ZDCs. It cannot
    be the same as for other detectors since 1 neutron will causes
    hundreds of e+e- pairs to cross the optical fibers. One method
    would be only to define the energy per event in each  module.
    Flemming asked me to impliment the next level of detail, ie the
    energy in each module per track. This is in principle possible
    since GEANT calls a user routine after it has finished processing
    each primary track. I can do this but not until I return to 
    Texas. Even their it will take me some time. However I will 
    get back to you about this.
                  Yorus Michael
