Type-Bound Procedures

procedure, public, pass(from) :: transform

coordinate transformation routine

  • private subroutine transform(from, rv, to, et, eph, rv_out, status_ok)

    Transform a Cartesian state from one reference frame to another at a specified epoch. The from and to reference_frames may each be defined at a different epoch. The et ephemeris time is the time the transformation is to be done, and accounts for the motion of the two frame centers from from%et and to%et to et.

    Arguments

    Type IntentOptional Attributes Name
    class(reference_frame), intent(inout) :: from
    real(kind=wp), intent(in), dimension(6) :: rv
    class(reference_frame), intent(inout) :: to
    real(kind=wp), intent(in) :: et

    the time of the transformation [sec]
    class(ephemeris_class), intent(inout) :: eph

    for ephemeris computations (assumed to have already been initialized)
    real(kind=wp), intent(out), dimension(6) :: rv_out
    logical, intent(out) :: status_ok
