NOVAS3Nutation Method
Nutates equatorial rectangular coordinates from mean equator and equinox of epoch to true equator and equinox of epoch.

Namespace: ASCOM.Astrometry.NOVAS
Assembly: ASCOM.Astrometry (in ASCOM.Astrometry.dll) Version: 6.0.0.0 (6.3.0.2839)
Syntax
public void Nutation(
	double JdTdb,
	NutationDirection Direction,
	Accuracy Accuracy,
	double[] Pos,
	ref double[] Pos2
)

Parameters

JdTdb
Type: SystemDouble
TDB Julian date of epoch.
Direction
Type: ASCOM.AstrometryNutationDirection
Flag determining 'direction' of transformation; direction = 0 transformation applied, mean to true; direction != 0 inverse transformation applied, true to mean.
Accuracy
Type: ASCOM.AstrometryAccuracy
Selection for accuracy
Pos
Type: SystemDouble
Position vector, geocentric equatorial rectangular coordinates, referred to mean equator and equinox of epoch.
Pos2
Type: SystemDouble
Position vector, geocentric equatorial rectangular coordinates, referred to true equator and equinox of epoch.
Remarks
Inverse transformation may be applied by setting flag 'direction'
