public static short Ecl2EquVec(
	double JdTt,
	CoordSys CoordSys,
	Accuracy Accuracy,
	double[] Pos1,
	ref double[] Pos2
)

Public Shared Function Ecl2EquVec ( 
	JdTt As Double,
	CoordSys As CoordSys,
	Accuracy As Accuracy,
	Pos1 As Double(),
	ByRef Pos2 As Double()
) As Short

Parameters

JdTt  Double

TT Julian date of equator, equinox, and ecliptic used for coordinates.

CoordSys  CoordSys

Coordinate system selection. 0 ... mean equator and equinox of date; 1 ... true equator and equinox of date; 2 ... ICRS

Accuracy  Accuracy

Selection for accuracy

Pos1  Double

Position vector, referred to specified ecliptic and equinox of date. If 'CoordSys' = 2, 'pos1' must be on mean ecliptic and equinox of J2000.0; see Note 1 below.

Pos2  Double

Position vector, referred to specified equator and equinox of date.

Return Value

            0 ... everything OK
            1 ... invalid value of 'CoordSys'
