virtual void Nutation(
	double JdTdb, 
	NutationDirection Direction, 
	Accuracy Accuracy, 
	array<double>^ Pos, 
	array<double>^% Pos2
) sealed

Parameters

JdTdb
Type: System..::..Double
TDB Julian date of epoch.
Direction
Type: ASCOM.Astrometry..::..NutationDirection
Flag determining 'direction' of transformation; direction = 0 transformation applied, mean to true; direction != 0 inverse transformation applied, true to mean.
Accuracy
Type: ASCOM.Astrometry..::..Accuracy
Selection for accuracy
Pos
Type: array<System..::..Double>[]()[][]
Position vector, geocentric equatorial rectangular coordinates, referred to mean equator and equinox of epoch.
Pos2
Type: array<System..::..Double>[]()[][]%
Position vector, geocentric equatorial rectangular coordinates, referred to true equator and equinox of epoch.

Remarks

Inverse transformation may be applied by setting flag 'direction'
