CL_fr_G502terMat

Description

• This function is deprecated.

  Replacement function: CL_fr_convertMat

• Computes the frame transformation matrix M from Gamma50 (Veis) to the terrestrial ("Earth fixed") reference frame.

  By convention, M multiplied by coordinates relative to G50 yields coordinates relative to the terrestrial frame.

• Notes:

  Transformation from Gamma50 (Veis) to terrestrial frame consists in a single rotation of the Veis sideral time (see CL_mod_sidTimeG50) around the Z axis.

• 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)

M:

Gamma50 (Veis) to terrestrial frame transformation matrix (3x3xN)
