CL_mod_nutationAngles

Description

• This function is deprecated.

• Computes the nutation angles (delta longitude, delta obliquity) according to Wahr nutation theory.

Parameters

jj_tai :

(integer) Modified (1950.0) Julian day (1xN)

sec_tai :

seconds (TAI time scale) (1xN)

flag :

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

NUT :

longitude, obliquity NUT=[DPSI;DEPS] [rad] (2xN)

F :

fundamentals arguments of nutation [rad] (5xN)

NUTP :

(optional with FP) first time derivative of NUT [rad/s] (2xN)

NUTPP :

(optional with FPP) second time derivative of NUT [rad/s^2] (5xN)

FP :

(optional with NUTP) first time derivative of F [rad/s] (2xN)

FPP :

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