Phrase: Barycentric Dynamical Time | Statement: [SSB, timeScalesReferencedTo, Barycentric Dynamical Time]

Target entity: Barycentric Dynamical Time
Context triple: [SSB, timeScalesReferencedTo, Barycentric Dynamical Time]

• A. Barycentric Dynamical Time chosen
  Barycentric Dynamical Time is a relativistic time scale used in celestial mechanics and ephemerides, defined for an observer at the solar system’s barycenter to accurately model planetary and spacecraft motions.
• B. Barycentric Celestial Reference System
  The Barycentric Celestial Reference System is a relativistic, solar-system–centered coordinate framework used in astronomy and astrometry to precisely describe the positions and motions of celestial bodies with respect to the solar system’s center of mass.
• C. Ephemeris Time
  Ephemeris Time is a former astronomical time standard based on the orbital motion of the Earth around the Sun, used to provide a uniform measure of time before being replaced by more precise atomic-based scales.
• D. Terrestrial Time
  Terrestrial Time is a modern astronomical time standard used for precise calculations of planetary motion and ephemerides, defined in relation to atomic time rather than Earth's rotation.
• E. Besselian year
  A Besselian year is a time interval used in astronomy, defined with respect to the Sun’s mean position relative to the stars and historically used as a reference for star catalogs and celestial coordinates.
• F. None of above.
• G. Unsure - the case is ambiguous/there is not enough information to decide.
