CVVUPickPeak Method

Find peaks in a VV - method one.

Namespace:  Geosoft.Desktop.GXNetX
Assembly:  geosoft.desktop.gxnetx (in geosoft.desktop.gxnetx.dll) Version: 2025.1.0.25
Syntax
Copy
public static void PickPeak(
	CGXNETCore gxNetShared,
	CVV vv_i,
	CVV vv_o,
	double pr_tol,
	int width
)

public static void PickPeak(
	CGXNETCore gxNetShared,
	CVV vv_i,
	CVV vv_o,
	double pr_tol,
	int width
)

Parameters

gxNetShared
Type: GeoEngine.Core.GXNetXCGXNETCore
A shared CGXNETCore
vv_i
Type: GeoEngine.Core.GXNetXCVV
Input VV
vv_o
Type: GeoEngine.Core.GXNetXCVV
Returned peak VV, all dummies except peak points.
pr_tol
Type: SystemDouble
Minimum value to accept (0.0 to find all)
width
Type: SystemInt32
Minimum width to accept (1 to find all)
Remarks
Peaks are the maximum point within a sequence of positive values in the input VV. The width is the number of points in the positive sequence. A VV may have to be pre-filtered before finding the peak values: Use BPFilt_VVU to smooth the data as required. Use Filter_VVU to apply a Laplace filter "-0.5,1.0,-0.5" to make curvature data.
