Peak localisation error is the Euclidean norm of the difference between true and estimated peak positions. Spatial dispersion walks the source list once, accumulating |a_k| * dist(k, peak) into the numerator and |a_k| into the denominator so the result is the amplitude-weighted mean distance from the estimated peak in the same units as the input positions (typically millimetres). findPeakIndex is a single absolute-value argmax over the amplitude vector.
