Hi everyone,

  

I  am giving artemis the following parameters:

                     

     guess amp  1

     def  delr  alpha*reff

     guess enot 0

     def  ss debye(temp,thetad)

     set alpha .0002

     set  thetad  343

     set  temp    298

   But I am not getting a very good fit. The value of debye temperature is 343 for Cu( Kittel book)  but I got to know that some persons even guessed the value of thetad as 285+-16 . I am not getting that how we can guess the value of alpha and thetad   . Also I am not getting the value of Ei, 3rd and 4th cumulant in the fit results . So How can I get the value of these parameters in the fit results .
