Dear Brian,
Nonetheless, the type 4 profile model has built-in constraints
according to the cell class -- so it is easy to use and refines with
far greater stablility that the Lxx terms. My advice to non-experts is
still the following:

Andreas,
What you say is good to know.

Dear Brian,
recently it was pointed out (J. Appl. Cryst. 37 (2004) 123-135) that the
approach proposed by Von Dreele can have indeed - under certain
circumstances and restrictions to the parameters - a physical meaning,
e.g. concentration fluctuations can show up like this, and the type of

My advice on this question is that one should not use this approach. The
Stephens formalism, coded in profile type 4, is better founded by
theory. See the GSAS manual and reference to Peter Stephen's J. Appl.
Cryst paper from a few years back.
