CL_mod_nutationArg

Description

• This function is deprecated.

• Computes the fundamental arguments for nutation (F) (Sun and Moon position), and their derivatives (FP,FPP).

  F(1,:) -> l = Mean Anomaly of the Moon

  F(2,:) -> l' = Mean Anomaly of the Sun

  F(3,:) -> F = L - OMEGA (where L is the mean longitude of the moon)

  F(4,:) -> D = Mean Elongation of the Moon from the Sun

  F(5,:) -> OMEGA = Mean Longitude of the Ascending Node of the Moon

Parameters

t :

Time from 1st January 2000 12h in centuries (number of days / 36525), (TT time scale) (1xN)

flag :

(optional) "n" -> F only; "p" -> F and Fp; "s" -> F, Fp and Fpp (default depends on number of output variables)

F :

Fundamental arguments for nutation (5xN) [rad]

FP :

(optional) First time derivative of F (5xN) [rad/s]

FPP :

(optional) Second time derivative of F (5xN) [rad/s^2]
