Yes, this is why I wanted to download corrected data back in PFE. BG can be non linear and I am not sure, is it possible to use exponential BG in the Fityk App.

I am sure you can figure it out.    :)

Could you tell how we can know the exactly function of line (with all parameters) which the system uses as BG.

The background fit methods are all documented in the Probe for EPMA User Reference manual.  However, note that for the purposes of APF determinations, the exact background fit may not be a critical since the APF equation cross multiplies the intensity terms.

Yes, thank you. I found it and calculated APF coefficients like I wanted.

Thank you very much!

Edit by John: I answered your question about importing MAN curves here:
