   * With the option to collimate part of this beam due to the differential pumping plate.
   * Initial distribution derived from smearing Phi from EPOCH simulations: /vols/ccap/data/LhARA/EPOCH_init.root 
+   * Generated from rootPhiSmear.cpp root macro
+   * To generate: rootPhiSmear.cpp(float keLowCut, float keUpCut, int numPart, bool writeAscii, TString fileName)
