Dear Hiro,
of course the best solution would be for me to
sum the energy created by each particle that hits the ZDC and
report that as a hit. This would give the most accurate
measure of the ZDCs performance. However since the ZDC response
varies little across the face of the ZDC you would not lose much
be doing what you suggest.
