    Database option for dispersion corrections df1, df2: 
   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 0.41-1240 A) -- recommended for soft X-rays
   Use Brennan-Cowan data (0.03-700 keV or 0.02-413 A)
   Use Windt data (0.01-100 KeV or 0.12-1240 A)
   Use Chantler data (0.01-450 KeV or 0.28-1240 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:
