NOVAS2COMNutate 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 (6.2.0.2774)
Syntax
public short Nutate(
	double tjd,
	NutationDirection fn,
	double[] pos,
	ref double[] pos2
)

Parameters

tjd
Type: SystemDouble
TDB julian date of epoch.
fn
Type: ASCOM.AstrometryNutationDirection
Flag determining 'direction' of transformation;
    fn  = 0 transformation applied, mean to true.
    fn != 0 inverse transformation applied, true to mean.
pos
Type: SystemDouble
Position vector, geocentric equatorial rectangular coordinates, referred to mean equator and equinox of epoch.
pos2
Type: SystemDouble
OUT: Position vector, geocentric equatorial rectangular coordinates, referred to true equator and equinox of epoch.

Return Value

Type: Int16
0...Everything OK.
Remarks
Inverse transformation may be applied by setting flag 'fn'.
