Hello List,
I'm having a strange problem with my EXAFS fits in Artemis in which they
seem to fly off at higher k. I was having trouble with background fitting
a particularly messy data set and I wanted more control over this so I used
the program PySpline to fit the background after I did the rest of the
preprocessing in Athena. I then imported the data into Athena and loaded
the project into Artemis. Interestingly, when I only include a single path
in the fit and plot both the single path and the overall fit, the single
path does not fly off but the overall fit does. I have attached an image
of the issue. When I use the spline fitting built into athena, I do not
encounter this issue. Has anyone ever experienced this issue before?
Thanks for your help!
