Hi Kotaro ATZ is the Z*Mw*f that you were calculating. You can find it described in the FullProf manual .pdf file around page 91 (or search for “ATZ”), and it is given for each phase in the line : !Nat Dis Ang Pr1 Pr2 Pr3 Jbt Irf Isy Str Furth ATZNvk Npr More You can calculate it you

Hi Josh Do you mean a standard for the peak positions, to correct for the sample shift? If so, then I'd say it depends on whether the mesh and sample are exactly on the same plane. And what type of in-situ? If it is temperature, then they should ideally have similar thermal expansion behavior as
