Dear ferrets,
I have a question concerning the shf transformation:

let sum_plus = temp+temp[j=@shf+1]
list sum_plus[j=500]
          
        5.466
list temp[j=500]+temp[j=501]
          
        5.466
ok, all fine.

BUT:
let sum_minus = temp+temp[j=@shf-1]
list sum_minus[j=500]
          
        5.466

gives the same as above and not:
list temp[j=500]+temp[j=499]
          
        5.268

Why is it set up this way ?  Or am I missing something ?

thanks! Alexa
