CL_mod_sidTimeG50

Description

• This function is deprecated.

  Replacement function: CL_mod_siderealTime

• Computes the sidereal time relative to Gamma50 Veis reference frame.

  It also optionally computes the first derivative of the sidereal time : gmstp, which is a constant value.

Parameters

cjd_ut1:

Modified (1950.0) julian day in UT1 time scale (1xN)

gmst:

Gamma50 Veis sidereal time [rad] (1xN)

gmstp:

Gamma50 Veis sidereal time first derivative [rad/s] (1xN)
