[Ifeffit] boundary issue in artemis

[mfehse]

Dear all,

im fitting Ti next neighbour environment and I'm facing the problem that 
above a k value of 9 the fit deviates completely and does not follow the 
data any more. I dont really understand what is happening, so im forced 
to limit my fitting window in order to avoid this effect.
i have attached a plot in k space so you can better understand what im 
talking about.

any hints would be appreciated
