Hello, I am trying to figure out how to access true particle information. Right now I return a Particle list from the LCDEvent, but this contains limited information. The MCParticle type contains the type of information I need, but I don't understand how one access's it. Specifically what I would like to know is the point where the particle enters the calorimeter and the momentum of that particle when it enters the calorimeter. Any help would be greatly appreciated. Thanks, Brandon
