Description

Models a parabolic mirror. The reflectivity profile is given by a 2-column reflectivity free
text file with format [q(Angs-1) R(0-1)].

Example:  Mirror_Parabolic(reflect="supermirror_m3.rfl", xwidth = 0.05, xshift=0.05,
yheight = 2e-4, focus = 6.6e-4)

Input parameters

Parameters in boldface are required; the others are optional.

Name	Unit	Description	Default
reflect	q(Angs-1) R(0-1)	(str) Reflectivity file name. Format	0
xwidth	m	width of the illuminated parabola	0.05
xshift	m	distance between the beam centre and the symetric axis of the parabolla	0.019
yheight	m	height of the mirror	2e-4
focus	m	focal length	6.6e-4
R0	1	Low-angle reflectivity	0.99
Qc	AA-1	Critical scattering vector	0.0219
alpha	AA	Slope of reflectivity	6.07
m	1	m-value of material. Zero means completely absorbing.	1.0
W	AA-1	Width of supermirror cut-off	0.003
