There is no need to generate 13 M GAMMA-GAMMA events. what is necessary is
to make a cut so that only events with pt>2 GeV are generated. I
believe such a cut exists. Please check with Nick Danielson
([log in to unmask]) as to what that cut is. That
should reduce the number of events generated by a factor of about 10.
