CL_fr_G502J2000Mat

Description

• This function is deprecated.

  Replacement function: CL_fr_convertMat

• Computes the frame transformation matrix M from Gamma50 (Veis) to EME2000.

  By convention, multiplying M by coordinates relative to G50 yields coordinates relative to EME2000.

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

Parameters

cjd:

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

ut1_utc :

(optional) ut1-utc [seconds] (default is 0) (1xN)

xp :

(optional) x polar coordinate [radians] (default is 0) (1xN)

yp :

(optional) y polar coordinate [radians] (default is 0) (1xN)

dPsi :

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

dEps :

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

conv_iers :

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

M:

Gamma50 (Veis) to EME2000 transformation matrix (3x3xN)
