Dear Experts, This might be an FAQ. Where (in which file) can I find correlation matrix in GSAS? Regards, Dan Shim

Rigid body constraints on perovskite structured materials

2004-11-11 Thread Sang-Heon Shim
Dear experts, I wonder if the rigid-body constraints of GSAS can be used for the polyhedra which are linked each other, such as octahedra in perovskite structured materials. Or is the application of the rigid-body constraints strictly restricted to isolated polyhedra in crystal structures?

GSAS with EDS data

1999-04-28 Thread Sang-Heon Shim
I am analyzing energy dispersive x-ray diffraction data. It looks to me that GSAS only supports Gaussian function for EDX data. Anyway I have big problem to fit profile function. After some point, calculated peaks won't be broadened, so that I have bad fitting situation. Further
