[Ifeffit] MBACK and Athena

[Christopher Patridge]

Hello Cyril,

Is there a particular reason for moving the data to Matlab and using 
MBACK rather than the built-in procedure in Athena?  From your email, it 
seems that you have the raw data which you then merge.  I would feel 
confident in performing all the data processing in Athena.  Your hope in 
merging data is remove noise and improve the confidence that features 
seen in the data are real.  Someone may be able to comment on the impact 
of MBACK, but questions here mostly deal with ifeffit.

Good luck,

Chris
