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 ******************************** Christopher J.

Hello,
I have 3 spectra taken from a single sample, I align, merge and save the merged data as merge.xmu file.
I then normalize this merged data using the MBACK algorithm in Matlab, the results of which is stored as merged.xmu.mnor file. This file, I then import to ATHENA using the instructions in http://www.mail-archive.com/ifeffit@millenia.cars.aps.anl.gov/msg03523.html.
I do this for all my samples and standards in order for me to perform LCF.
My questions are
1.Is this procedure valid? In the sense that no information or features of the spectrum are lost from merge.xmu to merged.xmu.mnor file.
2.How will the procedure <Calibrate data> affect this procedure?
Thank you for your time in answering my questions.
Regards,
Cyril
PS: This query is in relation to my previous question [Ifeffit] Basic question in normalization and background removal
