We have started working out the input file for FullProf, since we are 
quite familiar with this software and many people are,too, here in europe.
The pointer to the Carvajal paper was a good hint. Anyways, we use our 
mind and the manual of FullProf in first order to enter the parameters.
I heard allready that GSAS offers a lot of easyly handled features, but 
to get into (also to get it and set it up) the software takes time that 
we do not have at the moment.
Thanxalot again to all of you.
