   Auto (Henke at low energy, X0h at mid, Brennan-Cowan at high).
   Use X0h data (5-25 keV or 0.5-2.5 A) -- recommended for Bragg diffraction.
   Use Henke data (0.01-30 keV or 0.4-1200 A) -- recommended for soft x-rays.
   Use Brennan-Cowan data (0.03-700 keV or 0.02-400 A)

Find only those Bragg planes which make certain angles to the surface:  
    Surface plane indices:    
   Planes make angles from Theta1 to Theta2
   Planes make angles from Theta1 to (Bragg_Angle - Theta2)
   Planes make angles from (Bragg_Angle - Theta1) to (Bragg_Angle - Theta2)

    Theta1:       Theta2:
