Talk:Debye–Waller factor

The article still has serious problems.

• The B-factor, or temperature factor, is defined in the PDB as $B=8\pi ^{2}\left\langle u^{2}\right\rangle$. This has units (of Angstrom^2 in the PDB) and is distinct from the DWF as defined in the article. Indeed, high quality = low uncertainty = low value of this B (as stated in the article), while obviously for the DWF as defined in the article, high quality ~ 1, low quality ~ 0. I don't seem to find references that clarify the different uses of the terms.
• I have seen references that (in the terms of the above) $DWF=B\cdot \sin ^{2}(\theta )/\lambda ^{2}$. Using $q=4\pi \,\sin(\theta )/\lambda$ this seems to give $DWF=q^{2}\left\langle u^{2}\right\rangle /2$, while in the article it is explained why $DWF=q^{2}\left\langle u^{2}\right\rangle /3$. So it seems there's also some mixup in the coefficients.
