No! ENDRAW concerns energy deposition at a point, due to escape, time kill or
particle below energy threshold. Nothing to do with a shower vertex.
You could use USDRAW and look for an event of bremsstrahlung (if the incident
particle is an electron) or pair production (if it is a photon).
At the primary vertex, the generation number of the secondaries must be equal
to the generation number of the incident particle plus 1. If the shower is
generated by a primary particle, the generation of the secondaries must
be = 2.
The generation number is given by variable LTRACK, in COMMON TRACKR.
