Dear Matthew,
Following to Professor Daniel Chateigner 's email, I would like to highlight briefly that the preferred orientation (PO) directions for calcite (CaCO3) that we used during the refinement using GSAS were · <104> for X-ray diffraction data, and · <001> for neutron diffraction data. Please see the Curtin Library link<http://espace.library.curtin.edu.au/R?func=dbin-jump-full&object_id=10543> or IUCr Journal of Applied Crystallography, Volume 35, Part 2 (April 2002)<http://journals.iucr.org/j/issues/2002/02/00/issconts.html> and Volume 38, Part 1 (February 2005)<http://journals.iucr.org/j/issues/2002/02/00/issconts.html> for the details. With best wishes, Husin _______________________________________________________ Husin Sitepu, PhD SAUDI ARAMCO RESEARCH & DEVELOPMENT CENTER Dhahran, PO Box 31311, KSA Phone: +966 876-3050 Email: sitep...@aramco.com<mailto:sitep...@aramco.com> http://scholar.google.com/citations?hl=en&user=cUTV8HkAAAAJ&view_op=list_works&pagesize=100 _______________________________________________________ -----Original Message----- From: rietveld_l-requ...@ill.fr [mailto:rietveld_l-requ...@ill.fr] On Behalf Of daniel Chateigner Sent: Tuesday, March 25, 2014 2:10 PM To: rietveld_l@ill.fr Subject: Re: PO corrections in trigonal space groups? Hi Matthew, You would perhaps prefer physically meaningfull PO correction using standard functions, at disposal in Maud. If you can give me an ascii double column of your data I'll give it a trial. daniel Le 25/03/2014 11:43, Matthew Rowles a écrit : > Hi all > > I have a sample containing a fraction of calcite.
