Hello,
 
Questions from a beginner in EXAFS...using Athena and Arthemis
 
From where to get the error bars for number of neighbours, distance and sigsqr (ss)?
 
What are Chi-square,Reduced Chi-square and R-factor and how should be their values in a fit?
 
Sometimes it happen that "R-factor for this data set" does not have the same value as the first R-factor from results. Why?
 
many thanks,
 
Elena
