Amplitude normalization of the correlation curves allows you to compare different correlation curves and see the differences in diffusion times between them.

If the fit of the correlation curves is already done, activating the amplitude normalization is done using the amplitude fit parameter. Selected correlation curves are rescaled that each selected curve has a correlation amplitude equal to 1 (corresponding number of molecules = 1).

where A is a fitted amplitude.

In case no fit is done, correlation curves are normalized as follows:

where A_mean ​​ is the mean amplitude calculated over the first 10 points of the correlation curve:
