Detailed Description

EEMC tower to track matching.

This a MuDST based class to match TPC tracks to EEMC towers. Its main result is a list of towers with associated tracks (list of EEmcTTMatch objects)

Remarks

Bug:

The matching algorithm assumes that z depths at which matching is performed are in fact inside the EEMC, i.e. it is only phi and eta that are checked at given z. So it is up to the user to ensure that z depths are really inside EEMC. And the defaults are.

Since cint in root/root4star does not allow to pass function pointers (that would be ideal for user defineable EEmcTTMMaker::AcceptTrack and EEmcTTMMaker::MatchTrack) we're stuck with FORTRAN++
