Hi folks, I´ve been working on Xanes peaks fitting with Athena (last version) and I found a strange behaviour. I get a "good" fit looking to the Graphics Window of Athena and to the minimized parameters (R-factor, etc). However, when I use the data of the fit generated by Athena "write a log file" feature and plot them in Origin, the fit looks bad! In order to get a "good looking" fit in Origin I have to change the parameters ad-hoc in Athena fitting dialog box. When I do this, the fit looks bad in Athena Graphics window and better in Origin. The values that are inserted ad-hoc in Athena are not the optimized ones from the fitting procedure output. I have attached the log file from Athena fit and two figures: a PS figure from Athena and a JPG figure from Origin. It resembles that the generated data from Athena are not exactly these ones that I see in the Graphics window! I´m looking for help from someone out there. Kind regards, Ismael. -- Ismael Leandro Graff Departamento de Física - UFPR Centro Politécnico, CP 19044 81531-990, Curitiba, Brazil. Tel: +55 41 3361 3427 Fax: +55 41 3361 3418
