Triple

Given a phrase, classify it is english named entity (e.g., persons, organizations, works of art) in Latin script, or not (e.g., literals, dates, URLs, verbose phrases). For disambiguation, the statement where the phrase occurs as object is also given. Please return a JSON object with `phrase` (string, the phrase being analyzed) and `is_ne` (boolean, indicating whether the phrase is a Named Entity).

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

Target entity: ICRS
Context triple: [U Sagittarii, declinationCoordinateSystem, 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.
• G. Unsure - the case is ambiguous/there is not enough information to decide.

Target predicate: declinationCoordinateSystem
Context triple: [U Sagittarii, declinationCoordinateSystem, ICRS]

• A. declination
  Indicates the angular deviation of one direction or object from a reference plane or axis, typically measuring how far it is tilted or offset.
• B. equatorialCoordinateSystem chosen
  Indicates a relationship where an object's position is specified using the equatorial coordinate system, typically defined by right ascension and declination relative to the celestial equator.
• C. inclinationToEcliptic
  Indicates the angle between an object's orbital plane and the plane of the ecliptic, describing how tilted its orbit is relative to Earth's orbital plane.
• D. hasPlanetographicLatitudeDirection
  Indicates that something possesses or is associated with a specific directional component (e.g., north or south) of its planetographic latitude.
• E. equatorialCoordinateEpoch
  Indicates the specific reference date or epoch at which an object's equatorial coordinates (right ascension and declination) are defined or valid.
• F. None of above.
