Firstly, i'm very grateful for the useful responses from Bruce Ravel and Matt Newville on my previous question.

Now, I have another question about path. The screenshot below is the interpretation of a path in α-Fe. I was wondering what does "beta" means. Is that scattering angle? I tentatively construct a triangle according to the rleg values, and find that the three angles are consistent with the beta values. What does this mean? I searched the Artemis user guild and the mailing list, but could not find the answers. Do you have any ideas?

Thanks in advance
