	double x,
	double y,
	double[] pos1,
	ref double[] pos2
)
Visual Basic
Public Sub Wobble ( _
	x As Double, _

)
Visual C++
public:
virtual void Wobble(
	double x, 
	double y, 
	array<double>^ pos1, 
	array<double>^% pos2
) sealed

Parameters

x
Type: System..::..Double
Conventionally-defined X coordinate of rotational pole with respect to CIO, in arcseconds.
y
Type: System..::..Double
Conventionally-defined Y coordinate of rotational pole with respect to CIO, in arcseconds.
pos1
Type: array<System..::..Double>[]()[][]
Vector in geocentric rectangular Earth-fixed system, referred to geographic equator and Greenwich meridian.
pos2
Type: array<System..::..Double>[]()[][]%
OUT: Vector in geocentric rectangular rotating system, referred to rotational equator and orthogonal Greenwich meridian

Remarks

Corrects Earth-fixed geocentric rectangular coordinates for polar motion. Transforms a vector from Earth-fixed geographic system to rotating system based on rotational equator and orthogonal Greenwich meridian through axis of rotation.
