Dear Marcos: I think that you need to give us a bit more information. How much do you change the R-range? What do you mean by different? In general, a "good" solution should be robust to small changes in R-range but it is hard to be more specific. Cheers, Carlo On Sun, 12 Feb 2006, Marcos Eleoterio wrote:

Good morning,

I have a question about the R-range in Artemis, i want to fit the first shell region only, but what are the criteria to select the R-range? if i select the first peak just a,little bit different to one fit from the other, the fit get very different.
