ShiftGroupCollectionGetShiftOffset Method

Gets the shift offset. After creation of the master curve using the low level interface, the entire curve can be shifted, so that the value shift=0 is at another point. The point is determined by the options.

Namespace: Altaxo.Science.Thermorheology.MasterCurves
Assembly: AltaxoCore (in AltaxoCore.dll) Version: 4.8.3179.0 (4.8.3179.0)
Syntax
C#
Copy
public (double shiftOffset, double? referenceValue) GetShiftOffset(
	double? referencePropertyValue,
	bool useExactReferencePropertyValue,
	double?[] curveProperties,
	int indexOfReferenceCurve
)

Parameters

referencePropertyValue  NullableDouble
If not null, this is the reference value. Most probably in master curve construction, this is the reference temperature.
useExactReferencePropertyValue  Boolean
If true, the exact value given by referencePropertyValue is trying to use, even if this value is not the property value of any curve. In this case, the shift values are interpolated over the property values, and then the shift value is interpolated. If interpolation is not possible, the fallback method is then to not use the exact reference value.
curveProperties  NullableDouble
The properties of the curves. The array must have the same length as the number of curves in this instance. If referencePropertyValue is a reference temperature, then the values in this array must be temperatures, each temperature associated with a curve.
indexOfReferenceCurve  Int32
If referencePropertyValue is null, then the curve with this index is used as the reference curve. If at this index no shift information is available, then the curve nextmost to this index is used as the reference curve.

Return Value

ValueTupleDouble, NullableDouble
A tuple containing the shift offset, with which the entire curve should be shifted, and the actually used reference value (e.g. reference temperature).
