Hello, everyone, I have some questions about the refinement in Topas.
When we put the instrument parameters, we always include the LP factor, and set it to a constant value. I thought LP factor is a function of theta and not a constant value, so my question is what exact the constant value means. Why for unpolarized radiation, it is equal to 0, and for synchrotron radiation it is equal to 90. Sorry to throw so many questions.
Thank a lot for any help. Xiujun Li Master Student Advanced Materials and Processing Laboratory Chemical and Materials Engineering University of Alberta Edmonton, Alberta, Canada T6G 2G6 Phone: 1-780-492-0701
