NOVAS2Spin Method
Transforms geocentric rectangular coordinates from rotating system to non-rotating system

Namespace: ASCOM.Astrometry.NOVAS
Assembly: ASCOM.Astrometry (in ASCOM.Astrometry.dll) Version: 6.0.0.0 (6.3.0.2839)
Syntax
public static void Spin(
	double st,

	ref double[] pos2
)

Parameters

st
Type: SystemDouble
Local apparent sidereal time at reference meridian, in hours.
pos1
Type: SystemDouble
Vector in geocentric rectangular rotating system, referred to rotational equator and orthogonal reference meridian.
pos2
Type: SystemDouble
OUT: Vector in geocentric rectangular non-rotating system, referred to true equator and equinox of date.
Remarks
Transforms geocentric rectangular coordinates from rotating system based on rotational equator and orthogonal reference meridian to non-rotating system based on true equator and equinox of date.
