Name

CL_mod_nutationArg — Fundamental arguments for nutation

Calling Sequence

   [F[,FP[,FPP]]]=CL_mod_nutationArg(t[,flag])
   
   

Description

  • Calculate 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 :

(TT - 2000 January 1d 12h TT) where TT is in days/36525, terrestrial time (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]
