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!
