CL_fr_G502J2000

Description

• This function is deprecated.

  Replacement function: CL_fr_convert

• Converts position and (optionally) velocity vectors from Gamma50 (Veis) to EME2000.

  The jacobian of the transformation is optionally computed.

• See Reference frames for more details on the definition of reference frames.

Parameters

cjd:

modified julian day from 1950.0 (UTC) (1xN or 1x1)

pos_G50:

position vector relative to Gamma50 (Veis) [m] (3xN or 3x1)

vel_G50:

(optional) velocity vector relative to Gamma50 (Veis) [m/s] (3xN or 3x1)

dPsi :

(optional) Nutation corrections [radians] (default is 0) (1xN or 1x1)

dEps :

(optional) Nutation corrections [radians] (default is 0) (1xN or 1x1)

conv_iers :

(optional) Convention IERS. Only iers 1996 (Lieske/Wahr) is implemented (default is "iers_1996")

pos_J2000:

position vector relative to EME2000 [m] (3xN)

vel_J2000:

(optional) velocity vector relative to EME2000 [m/s] (3xN)

jacob:

(optional) jacobian of the transformation (6x6xN)
