I've recently been trying to use Larch instead of Athena for EXAFS analysis, and I mainly do linear combination fitting for my samples. It seems that the XANES fitting is doing just fine requesting a specified region to fit (-25 to +75 eV). When I try to fit in the k-space however, Larch does not request a specific region in k space. I try to input the eV values corresponding to the k value I want to fit, but it is still plotting in mu rather than k . Is there anyway I can change this and/or do it manually on the larch GUI? Any help would be appreciated!

Thanks,

Garret
