[sdpd] Problems with Chi2 and WRp

["higorfav" <higorfav...@yahoo.com.br>]

Dear all,

I have a synchrotron powder diffraction file, and I've tried to make a
rietiveld refinement using a GSAS program.
The problem is that I'm just reaching  Chi2 less than 1, which
according to theory means poor data, and I also couldn't reduce the WRp.
My best WRp was 11% for Chi2=0.1109 , but observing the fitting, it
shows a good refinement (i guess I couldn't post the graph!) . Could
someone help me please?

Thank you in advance.

Higor.
