Stephanie,
The GSAS routine REFLIST has an option to produce a "single phase ascii" file
of reflections. One of the columns in that file is FWHM. Alternatively there is
a graphic in EXPGUI (widplt) that will plot FWHM and its Gaussian & Lorentzian
contributions as a function of 2-theta.

Sajeev,
There is a lot of information like this in the GSAS Manual.

Hello,
I am trying also to calculate crystal size from GSAS, and I want to find
back the fwhm of all the peaks from their position: how is it possible?
Thanks

Hi,
I am wondering if GSAS calculates the crystal size? If not how can I
calculate the crystal size? I am using a profile type 3 function (psedo
voight) and obtaining the GU,GV,GW values as 0,0, 1.27 E+04 for a Pt/C
phase respectively. The Chi-square fit is 2.164. Thankyou.
regards,

Hold that thought.
On closer examination of the difference plot at high angles you have something
that looks like sample displacement, and refining it improves the fit, although
the values for zero point and shift become quite large. Mirrors shouldn't give
you this kind of error so make sure it
I'm not sure exactly what your description of your setup means - do you have a
single or twin mirror system? I'm hoping that it's single because your
background is way too high for a properly aligned twin mirror system. I'm
assuming that you're using GSAS given the data format.
Your pattern r

Indeed it does! INSTRM=10 is x, y, sigma format for fullprof where it
10 matches
