 double xmax,
 double ymin,
 double ymax,
 double zmin,
 double zmax,
 double pmin,
 double pmax,
 double thetamin,

For setting up an array of initial values for testing. In cases where the difference between a min val and a max val is invalid input: '<' SMALL, the min val is used and the variable is no randomized.

Parameters:

rand - and random number generator

num - the number to create

charge - the integer charge

randCharge - if true the charge will be 1 or -1 randomly

xmin - minimum value of the x coordinate in meters

xmax - maximum value of the x coordinate in meters

ymin - minimum value of the y coordinate in meters

ymax - maximum value of the y coordinate in meters

zmin - minimum value of the z coordinate in meters

zmax - maximum value of the z coordinate in meters

pmin - minimum value of the momentum in GeV/c

pmax - maximum value of the momentum in GeV/c

thetamin - minimum value of the polar angle in degrees

thetamax - maximum value of the polar angle in degrees

phimin - minimum value of the azimuthal angle in degrees

phimax - maximum value of the azimuthal angle in degrees

Returns:

an array of initial values
