Hi, I suspect that the k-weighting for the plots are actually different. I played around with your data and I get the same plot for Artemis and Athena. However, Artemis might be a little confusing in that it has two controls for k-weight. On the left side you have the fitting controls including fitting range and k-weight. On the right you have plotting controls including range and k-weight. These controls are independent which means that the plot can be different than the fit. Try plotting in k space first and check that the y-axis scale is the same for both. Unfortunately, I was not able to duplicate file output problem . I selected the data and used the file menu to output to a file and it worked. Cheers, Adam Makoto Matsuura wrote:
Hi!
I'm annoyed with the mismach of Fourier transform between Athena and Arthemis. The k-weighting (k^1), k-window( Kaiser Bessel) and k-range are kept same for both. The input chi-data and resultant Fourier transforms are attached.
One more question of Arthemis is that when I try to output data of chi(k) or chi(r) from menu of File, null data file comes out while right data can be obtained for the fitted data. How can I get data of chi(k) or chi(r) in ascii format for Arthemis? Thank you. ======================================================================== Makoto Matsuura
