NOVAS31FundArgs Method
To compute the fundamental arguments (mean elements) of the Sun and Moon.

Namespace: ASCOM.Astrometry.NOVAS
Assembly: ASCOM.Astrometry (in ASCOM.Astrometry.dll) Version: 6.0.0.0 (6.2.0.2774)
Syntax
public void FundArgs(
	double t,
	ref double[] a
)

Parameters

t
Type: SystemDouble
TDB time in Julian centuries since J2000.0
a
Type: SystemDouble
Double array of fundamental arguments
Remarks
Fundamental arguments, in radians:
   a[0] = l (mean anomaly of the Moon)
   a[1] = l' (mean anomaly of the Sun)
   a[2] = F (mean argument of the latitude of the Moon)
   a[3] = D (mean elongation of the Moon from the Sun)
   a[4] = a[4] (mean longitude of the Moon's ascending node);
                from Simon section 3.4(b.3),
                precession = 5028.8200 arcsec/cy)
