Dear Bob,
yes, I know that, but there I can only select parameters from file, or
reset to default values. There is no way to chose different type of
default profiles, the same way it can be done when you load histogram
and press 'cancel' on profile prompt.

Dear Bartlomiej,
There are Save & Load menu items in Instrument Parameters for saving a
set of profile coefficients & then reading them in. If you do this for
the same histogram, it will reset the default values.

Thank You Brian,
i did it exactly same thing, but I was thinking that maybe someone
here did measurements on this very equipment and got the parameter file.
However, I've got another question, this time about GSASII menus. The
instrument parameters that can be refined for typical XRD are
slightly different than these for synchrotron. E.g., for XRD we can
select the type of radiation, and for synchrotron the wave length. Is
there any way to change the parameters set, other than removing the
histogram and adding it again?

You might try one of the generic parameter sets (press cancel at the
parameter dialog) or just start with peak fitting to get parameters
from the pattern you have, (see Determining Starting Profile
Parameters from a Standard
<https://subversion.xray.aps.anl.gov/pyGSAS/Tutorials/CWInstDemo/FindProfParamCW.htm>).
Either way you will not be able to get useful information on size
and microstrain, but you can start without an instrument parameter
file.

Dear all,
My colleague got a pattern from a synchrotron 'BL02B2 — SPring-8'.
I tried to help him with the refinement; however, it's my first
attempt to fit synchrotron data and we don't have the parameter
file. The colleague wrote an email to the operators, but we didn't
get any response. I'm wondering if anybody did some measurements
there and got the parameters? I will appreciate any help.
I post the link to the website of the synchrotron.
