Parameters

vv_i
Type: GeoEngine.Core.GXNetCVV
[i] data VV
vv_x
Type: GeoEngine.Core.GXNetCVV
[i] X VV used to calculate distance
vv_y
Type: GeoEngine.Core.GXNetCVV
[i] Y VV used to calculate distance
pr_base_lvl
Type: SystemDouble
[i] minimum value to accept (0.0 to find all)
pr_ampl
Type: SystemDouble
[i] amplitude
v_vind
Type: GeoEngine.Core.GXNetCVV
[o] Indices with peak locations
v_vamp
Type: GeoEngine.Core.GXNetCVV
[o] Amplitudes at the peaks
v_vwid
Type: GeoEngine.Core.GXNetCVV
[o] Anomaly widths
v_vhawid
Type: GeoEngine.Core.GXNetCVV
[o] Anomaly half-amplitude widths
Remarks
Uses Method 2 above, but also returns the anomaly width (defined as the distance between the surrounding troughs), and the width at the half-amplitude. The half-amplitude width is calculated in two parts, individually for each side based on the distance from the maximum to the location where the amplitude is mid-way between the maximum and trough. The returned VVs are packed; no dummies. Instead the indicies of the peak locations are returned.
