Piezo lag correction in:

What happens if the frequency of oscillation is not in the list of piezo-characterization? I think that we should interpolate an calculate a value of fi in that case.

Also, the tolerance should be better calculated from the ratio of the frequencies between experimental (f_exp) and expected (f_theor) and not the difference. Maybe the abs(f_exp/f_theor-1). And maybe we should use a lower value.

At the moment if the frequency is not in the list no correction is applied. The piezo lag is set to 0 deg and the amplitude quotient is set to 1.

We can call and discuss about how to implement the interpolation.

I agree about how the tolerances are calculated right now is not the best. We can discuss that too. I will send an email
