Dear Rietvelders
How come the error in peak position that is determining by a fitting process is smaller than the systematic error in d-space? Following Bragg equation, the smallest error one can have in calculating d-space is determine by the systematic error that followed by the goniometer scanning step. The smallest the scanning step the smallest is the systematic error in d-space. Apparently, a fitting process of an XRD reflections, say split Pearson VI, ends up with an error in peak position (which is the d- space) smaller than the systematic error. 1. Is it legitimate? Namely, can I address and report such error? 2. I used PDXL-2 for fitting. Did someone encounter such thing before?
