Good day,
I need to perform refinements using WAXS data; however, since this type of data isn’t commonly used for refinements I do not have the instrument parameters for TOPAS, but I was able to get the instrument parameters for GSASII from the instrument scientist. I was wondering if there is a straightforward approach to convert the instrument parameters from GSASII to Topas.
Any help would be will be very appreciated.
Here are the instrument parameters for GSAS II.
#GSAS-II instrument parameter file; do not add/delete items!
Type:PXC
Lam:0.5904000766343666
Zero:0.0
Polariz.:0.99
U:157.76993677745568
V:-13.207698320593412
W:4.733764728450379
X:0.0
Y:0.0
Z:0.0
SH/L:0.003030940088332733
Azimuth:0.0
Bank:1
The WAXS data was measured using a synchrotron instrument, Debye-Scherrer geometry, area detector based, powder diffraction device.
Best,

Here's a quick run down

See emission profile in Technical Reference, ie,
lam la 1 lo 0.5904000766343666 lh 0.01
>Zero:0.0
Zero_Error(0)
search for th2_offset in Technical Reference
>Polariz.:0.99
Do a search on the TOPAS Wiki

I think this has something to do with axial diveregence

Dont know what this is

This is think is simply a data file.
