[Wien] [SPAM?] unit in output spectra of TELNES3

[ZhenChen]

Dear wien2k users,
    I'm interested in the absolute value of the cross section of the scattered atom, so using TELNES3, I calculate the energy dependent ELNES, 
such as O_K edge for only one equivalent O atom in the unit cell. If I integrate the calculated spectra, I will get the total cross 
section within an energy window. 
So my question is :
  What is the unit of spectra values in case.broadspec? Is it a.u.^2/eV? As I saw the comment in the source code (modula.F) that "we work in atomic units".
By the way, for the averaged spectrum, is the final (single) differential cross section divided by 4*pi or not (that is,scattered events per solid angle or the whole solid angle?)?
  Any response will be appreciated!

Best regards,
Zhen Chen
