Description

For mono_ideal=0 the Single_crystal component is used as monochromator,
for mono_ideal=1 Monochromator_curved is used with the same settings.

The curvature of the monochromator can be set using mono_curvh and mono_curvv
for horizontal and vertical focusing, respectively.
For mono_curvh=0, mono_curvv=0 the monochromator is flat.
For mono_curvh=-1, mono_curvv=-1 optimal horizontal and vertical focusing is chosen.

Input parameters

Parameters in boldface are required; the others are optional.
