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: International Celestial Reference Frame | Statement: [International Celestial Reference System, realization, International Celestial Reference Frame]

Target entity: International Celestial Reference Frame
Context triple: [International Celestial Reference System, realization, International Celestial Reference Frame]

• A. International Celestial Reference System
  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.
• 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. International VLBI Service for Geodesy and Astrometry
  The International VLBI Service for Geodesy and Astrometry is an international organization that coordinates Very Long Baseline Interferometry observations to provide precise measurements of Earth’s rotation, reference frames, and celestial positions.
• D. 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.
• E. IERS Conventions
  IERS Conventions are a set of internationally recognized technical standards and models that define how to precisely measure and reference Earth’s rotation, orientation, and reference frames for geodesy and astronomy.
• F. None of above. chosen
• G. Unsure - the case is ambiguous/there is not enough information to decide.

Generate a one-sentence description of the target entity. 
You are given a context triple in the form (subject, predicate, object), where the object is the target entity. 
# Instructions
Use the triple to infer relevant information about the entity. Describe the entity based on what is most defining, well-known. 
Avoid repeating the information from the triple, unless really essential.
# Response Format
Return only the sentence: "Description: [one-sentence description of the target entity]"

Entity: International Celestial Reference Frame
Triple: [International Celestial Reference System, realization, International Celestial Reference Frame]

The International Celestial Reference Frame is the fundamental astronomical reference frame that defines precise positions of distant extragalactic radio sources to serve as the standard background grid for celestial coordinate measurements.
