Pol_guide_vmirror Component
Models a rectangular guide with entrance centered on the Z axis and
with nvs x two supermirrors sitting in v-shapes inside.
The entrance lies in the X-Y plane. Draws a true depiction
of the guide with mirrors, and trajectories.
The polarisation is handled similar to in Monochromator_pol.
The reflec functions are handled similar to Pol_mirror.
The up direction is hardcoded to be along the y-axis (0, 1, 0)
The reflectivity parameters can be
1. double pointer initializations with 5 parameters (e.g. {R0, Qc, alpha, m, W} AND inputType=0), or
2. double pointer initializations with 6 parameters (e.g. {R0, Qc, alpha, m, W, beta} AND inputType=0), or
3. table names (e.g."supermirror_m2.rfl" AND inputType=1), or
4. individually assigned values (e.g. rR0=1.0, rQc=0.0217, ... etc AND inputType=2).
NB! This might cause warnings by the compiler that can be ignored.
Note that the reflectivity functions that use with values and those that use tables are different.
GRAVITY: YES
%BUGS
