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: 3c9121baba46811fe6e53a58a05935662261416d
public void FundArgs(
	double t,
	ref double[] a


Type: SystemDouble
TDB time in Julian centuries since J2000.0
Type: SystemDouble
Double array of fundamental arguments
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)
