Amplitude Precorrection

The procedure for amplitude precorrection is the same as that for phase precorrection.
If the first interpolation point brings about an improvement, deal similarly with the other in-
terpolation points.
1. Set the interpolation points more or less at the positions of the phase values.
2. Set all magnitudes to zero.
3. Starting with the interpolation point for the white level (low), change the magnitude (in
steps of ± 0.5 or smaller) in order to find the precorrection.
From here on it is a prerequisite that the precorrection for phase and amplitude has been

optimized at all interpolation points.
