[Ifeffit] Merging data in Athena

It seems rather unconventional to try and merge data which has different 
energy grid spacing?  I thought the main point of merging data is to 
reduce the noise and uncertainty of a measurement.  I am not sure how 
the exact method of merging data is implemented but I don't think it is 
fair to call this a bug as a result of a unique situation.  Could you or 
have you reinterpolate one spectrum?
