[sdpd] funtamental profile parameters U, V, W ?
Dear All,
I'm having pain in estimate the initial value for U, V, W for extracting structure factors by Fullprof. I often got error the message "square of FWHM <0".
Could anyone tell me how what's the general approach to estimate these funtamental parameters? (Especially for synchrotron powder diffractometers)
Thank you very much for your kind help!
Sincerely Yours,
