File:LUND Spread.C

The LUND file is created by creating an isotropic distribution of particles within the Moller Center of Mass frame of reference. These particles are uniformly distributed through the angle theta with respect to the beam line in the range 90-180 in the Center of Mass frame. This is done at a set angle phi (10 degrees) with respect to the perpendicular components with respect to the beam line.
