Thank you for providing support for this question. In addition I'll emphasize that NR,NT determine a numerical integration mesh and should simply be converged. I'd expect NR=50 to be pretty good, and NT=1 to be ok at that level. The value *you* need will depend on the edge and on the values of the collection and convergence angle. (If you go out to large scattering angles, the logarithmic mesh can help doing so with a reasonable number of points without losing the small angle part.) Note that the mesh contains NR^2 NT points, so the telnes program slows down significantly as you increase NR.<div>
<br><div><br></div><div>To the OP: if you're unsure about the outcome of your calculations, feel free to send to me to look over and make sure you're getting sensible results. The whole Euler angle setup is perhaps not the most intuitive way of doing things; you are certainly not the first to be confused by it.</div>

<br>
Hello.<br>
I contacted Prof. Kevin Jorissen, who is the main developer of TELNES,<br>
with Prof. Peter Blaha's help.<br>
The Euler angles (0,0,0) of "Orientation Sensitive" means that the<br>
electron beam is parallel to the c-axis<br>
of the crystal.<br>
<br>
<br>
ORIENTATION SENSITIVE<br>
alpha beta gamma<br>
→<br>
1.rotate alpha degrees about z-axis<br>
2.rotate beta degrees about y-axis<br>
3.rotate gamma degrees about z-axis<br>
<br>
<br>
In addition, ORIENTATION SENSITIVE mode needs bigger values of NR and/or<br>
NT as far as I know.<br>
In my case, NR is 50.(30 was too small)<br>
<br>
Best wishes<br>
<br>
