Andy sent this accidentally to the list, but since it went there I will
reply to the list....
The PDF is also the simple sum of the two phases.
Our PDFfit profile fitting program allows fitting multiple phases in
much the same way as Rietveld programs. The program can be downloaded
from sourceforge.
On this topic, we will be releasing a new version of PDFfit a little
later in the year with a number of bug-fixes and better functionality,
so if you are using PDFfit, make sure you upgrade at that time.

Hi Simon,
We have a question about pfd analysis. If my sample is two
phase, so the diffraction pattern is the sum of two individual patterns,
what does the G(r) show? Is it just the sum of two individual G(r)s or
some mangled convolution between the two?
Cheers
Andy
