std::enable_if_t< centers::has_center_transform_v< C, TargetC >, Position< TargetC, F, U > > siderust::cartesian::Position< C, F, U >::to_center ( const Time< TT, JD > & jd ) const

inline

Transform this position to a different reference center (same frame).

The FFI center-shift uses VSOP87 ephemeris vectors expressed in EclipticMeanJ2000. When the position is already in that frame the FFI call is made directly; otherwise the position is first rotated to ecliptic, shifted, and rotated back so the result is frame-correct.

Template Parameters

TargetC Destination center tag.

Parameters

jd	Julian Date (TT) for the ephemeris evaluation.

std::enable_if_t< frames::has_frame_transform_v< F, Target >, Position< C, Target, U > > siderust::cartesian::Position< C, F, U >::to_frame ( const Time< TT, JD > & jd ) const

inline

Transform this position to a different reference frame (same center).

Only a pure rotation is applied; the reference center is unchanged. Only enabled when a FrameRotationProvider exists for the pair (F, Target).

Template Parameters

Target Destination frame tag.

Parameters

jd	Julian Date (TT) for time-dependent rotations.

inline

Combined frame + center transform in one call.

rotate to EclipticMeanJ2000
shift center
rotate to target frame
