I was thinking on whether PDFgetX3 applies any corrections on the input data and based on the book "Underneath the Bragg Peaks: Structural Analysis of Complex Materials" and some other articles, the intensity must be cleaned from background and also corrected for polarization factor.
I tested it with my data and when I applied polarization factor on my intensities, converted them to G(r) and refined, rw values increased very much and fit parameters changed slightly compared with I already had without polarization factor.
My main question lies here:
How does pdfgetx correct for polarization of x rays and also background etc.?
Thanks in advance for any help.
