[Ifeffit] How to assign measure unit to XAFS data

[Alexey Boubnov]

Dear Matteo,

µx that you measured is dimensionless: x in the thickness (in cm) and µ the
Absorption coeffiecient (per cm). Indeed, if you want to know the
Absorption coefficient µ of your sample, you should divide µx by x.

All the best,
Alexey
