Detailed Description

Physics generators for neutrinos, cosmic rays, and others.

Enumeration Type Documentation

anonymous enum

Enumerate mother codes for primary particles.

Normally the mother code for a primary particle would be set to some arbitrary invalid value like -1, however, we can use this to mark the source of the particle as being either, eg., neutrino induced or from cosmic-rays.

Enumerator

{

  // the maximum allowed seed for the art::RandomNumberGenerator
  // is 900000000. Use the system random number generator to get a pseudo-random
  // number for the seed value, and take the modulus of the maximum allowed 
  // seed to ensure we don't ever go over that maximum
  
  // Set gRandom to be a TRandom3 based on this state in case we need to pull
  // random values from histograms, etc
  TRandom3 *rand = new TRandom3(0);
    gRandom = rand;
    return rand->Integer(900000000);
