Optimizes the pulse position using sub-sample shifting. After Peak Opt the peak of the pulse will be situated on an integer sample number, rather than between samples.
If a measurement was carried out without PeakOpt, or if an external pulse was loaded or the peak of the pulse was previously moved by SubsampleShift, the maximum of the peak can be drawn back onto an integer sample. This helps with the consideration, congruence analysis of two impulses, or the IACC evaluation.
The actual data (amplitude, etc.) are not changed. (only the excess phase in the decimal area)
