Input parameters

Parameters in boldface are required; the others are optional.

Name	Unit	Description	Default
pol		If "x","y", or "z" set polarization along that axis. If "0" use a zero polarization.	"y"
lamb_1	AA	Lower wavelength limit to simulate	1
lamb_2	AA	Upper wavelegnth limit to simulate	10
RANDOM		Randomize polarization vector in the (ideal) polariser	0
polval		Set polarization to (polval,polval,polval). Gets overridden by pol	1
POLHE		Polarization of the 3He-gas in the cell.	0.7
