Hi Bruce, Now this is clear. In my case the correction I have to perform requires these measured/evaluated parameters: chi, mu (not sure if it's better to work with normmu here) and the background function. Is it physically meaningless to have the mu(k) and bkg(k) data? If that is not the case I would like to have these two columns exported in the ascii chi(k) file. So then I can perform the correction and re-import the new corrected chi(k) and make comparison with the uncorrected. Kind regards, Matteo 2016-04-01 15:06 GMT+02:00 :

Hi Bruce, this message il linked to the previous solutions you find for me.

For the reference, I asked to have a column of the chi(E) in the exported mu(E) data. This has worked correctly so far.

Now for my master thesis, I'm performing a correction to chi(E) in the E space regarding to some geometrical properties of the sample. I have also tried to re-import the corrected data as a chi(k), having reproduced the right k grid column, but it looks totally wrong. The thing I'm not sure about is if the chi(E) needs to be fourier trasnformed into chi(k) or not. That's because I would have liked to make comparison in the Athena software between the two chis, but if that's not possible I will keep it to the external software (mathematic) with which the correction is performed. Or if you can share me the fourier transform routine performed I can include it to my correction script.

Hope the message is clear, Kind Regards,

Matteo
