Gerard,

In GSAS there is a GENLES "print" option that will give the covariance terms larger than +/- 0.5 in the list file. There aren't as many large ones as you might think apart from the various background terms.

Dear all,

 

I suspect that in my rietveld refinements i have severe correlation problems. Is there any way of having a look at the matrix where this correlations are stood out?

 

Thanks
