Although it was mentioned very briefly in the technical manual I'm wondering how to do a LeBail refinement in TOPAS GUI and Launch mode. The latter seems to give an output in JEdit but no key is given for how to describe the outputs so I'm unsure how to interpret it fully.
I'm doing this for my studies to better estimate the lattice parameters of mullite solid solutions in coal fly ashes. I would appreciate any help thank you! 🙂
