On the other hand, you are correct that data only gets plotted in R up to 10 A. That was not a conscious decision by me and seems to be some kind of default in Ifeffit. Matt, how does one change that default?
You can set the maximum R for chi(R) from fftf() with fftf(data.chi, kmin=2,kmax=19, rmax_out=15)
This seems like a good thing to add as a configuration option in the next stable version of Artemis. I am open to votes for what the default value should be. I am leaning towards either 10 or 12. Matt, the fftf() page in the reference manual does, in fact, mention rmax_out, but only tangentially. Could you add its description to the parameter list?
