CosmicGeneratorCfg()

def CosmicGeneratorConfig.CosmicGeneratorCfg	(		flags,
			name = "CosmicGenerator",
		**	kwargs
	)

Note that in this coordinate frame the y-axis points upward such that the cosmics arrive from upward to downward in y.

The production vertex of cosmics is randomly distributed (flat) in the x-z plane with boundaries given below. The energy range is given as well.

The following settings are tuned to scintillators of dimensions 140 x 0.5 x 100 cm^3 placed at +-115.0 cm
