Hi all, I have some data that I have collected on our SCXRD diffractometer and I am keen to try and fit the data to extract unit cell parameters through a basic Pawley refinement. Something I am not sure about is the LP factor I should be using because I am unsure of the monochromation in the source (an Incoatec IuS microfocus source). If I let the LP_factor refine, it will converge at 90 degrees, but Im not sure if this should be expected. Does anyone here have any experience of refining data collected on a SCXRD instrument?
