[Ifeffit] Error in running Artemis - Rmin too smaller than Rbkg

Dear all,

I am facing this error when I try to run a fit. The file in question required a larger than normal Rbkg value of 3.0.

I have attatched the Athena file & the subsequent Artemis project file that I tried to fit so you can see the error I am facing.

>From what I can understand, I need to reduce the Rbkg value in the Athena file to a lower number. But whenever I try to do this it causes the background function to mess up which then also causes problems for the fit in 'R' space.

Is this problem because I have badly modeled the data badly in Athena to begin?

I'm not really sure how to solve the problem so your help and advice is much appreciated!

Many thanks,
