Re: [Ifeffit] How to fit "N" number of Neigbors in (D)Artemis?

2012-08-20 Thread Scott Calvin
Just to fill out some details about how this somewhat quirky aspect of Ifeffit/Artemis can be used: Suppose you want to find the degeneracy of nearest-neighbors, represented by path 1, and next-nearest neighbors, represented by path 2. To fit the degeneracy of one of the paths, 1. Set "N" to 1

Thanks. In this case, is the number of neibors equal to N * SO2 in the model result? Regards HM Bruce Ravel 写: > On Monday, August 20, 2012 09:02:28 PM Huaming Guo wrote: >> I am using the (D)Artemis for EXAFS fitting. However, the "N" is set to be a >> constant in the (D)Artemis. We can not

Hi, Bruce, Does that mean each shell has a different S02 value? Wei On Mon, Aug 20, 2012 at 9:44 AM, Bruce Ravel wrote: > On Monday, August 20, 2012 09:02:28 PM Huaming Guo wrote: > > I am using the (D)Artemis for EXAFS fitting. However, the "N" is set to > be a > > constant in the (D)Artemis.

Dear Colleague, I am using the (D)Artemis for EXAFS fitting. However, the "N" is set to be a constant in the (D)Artemis. We can not set the variable for this parameter. How can I do that if I model non crystalline samples using (D)Artemis? Thanks a lot. Regards Huaming Guo --
