Crystal with external profile gives bad results for polychromatic source #206

Closed srio closed 4 years ago

srio commented 4 years ago

the option of external profile does not produce the desired Z(energy) dispersion . It works only for monochromatic sources. I guess that it calculates the ray reflectivity interpolating in the reflectivity curve for (theta_incident-theta_bragg), but theta_bragg must be calculated for each ray taken into consideration its particular energy.

That was not designed for polichromatic source, since the diffraction profile is for one energy only. It can be changed, but this is not a bug.

Modified in ShadowOui 1.5.45, now it manage the polychromatic.

Input file must be: Th-Th Bragg, Reflectivity
