NovasFundArgs Method

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

Definition

Namespace: ASCOM.Tools.Novas31
Assembly: ASCOM.AstrometryTools (in ASCOM.AstrometryTools.dll) Version: 3.0.0-rc.1+86c25ce733aebb4d8b1b8a62e84770ea5e972bea
C#
public static void FundArgs(
	double t,
	ref double[] a
)

Parameters

t  Double
TDB time in Julian centuries since J2000.0
a  Double
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)
