Phrase: ICRS | Statement: [U Sagittarii, rightAscensionCoordinateSystem, ICRS]

Target entity: ICRS
Context triple: [U Sagittarii, rightAscensionCoordinateSystem, ICRS]

• A. IERS ICRS Centre
  The IERS ICRS Centre is the component of the International Earth Rotation and Reference Systems Service responsible for realizing, maintaining, and providing access to the International Celestial Reference System used for precise astronomical and geodetic measurements.
• B. International Celestial Reference System chosen
  The International Celestial Reference System is the standard, high-precision coordinate framework used in astronomy and geodesy to define positions of celestial objects relative to distant quasars.
• C. ICRF
  ICRF is the International Celestial Reference Frame, a highly precise, radio-source-based coordinate system used as the fundamental reference for positions in the sky in modern astronomy and astrometry.
• D. 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.
• E. ICRS Centre
  The ICRS Centre is a scientific institution responsible for maintaining and providing access to the International Celestial Reference System used for precise astronomical and geodetic measurements.
• F. None of above.
