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: Cosmicflows-2 data set | Statement: [Laniakea Supercluster, observedUsing, Cosmicflows-2 data set]

Target entity: Cosmicflows-2 data set
Context triple: [Laniakea Supercluster, observedUsing, Cosmicflows-2 data set]

• A. Laniakea Supercluster
  Laniakea Supercluster is a vast cosmic structure encompassing the Milky Way and hundreds of thousands of other galaxies, forming one of the largest known galaxy superclusters in the observable universe.
• B. Monoceros Ring stellar stream
  The Monoceros Ring stellar stream is a vast, ring-like structure of stars encircling the Milky Way, thought to be the remnant of a disrupted dwarf galaxy.
• C. FLRW cosmological models
  FLRW cosmological models are a family of solutions to Einstein’s field equations that describe a homogeneous and isotropic expanding or contracting universe, forming the standard framework for modern cosmology.
• D. Magellanic Stream
  The Magellanic Stream is a vast, trailing ribbon of gas stretching across the sky, stripped from the Magellanic Clouds as they interact gravitationally with the Milky Way.
• E. Sagittarius Stream
  The Sagittarius Stream is a vast, looping ribbon of stars encircling the Milky Way, created as tidal forces tear apart the infalling Sagittarius Dwarf Spheroidal Galaxy.
• 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: Cosmicflows-2 data set
Triple: [Laniakea Supercluster, observedUsing, Cosmicflows-2 data set]

The Cosmicflows-2 data set is a large compilation of galaxy distance and velocity measurements used to map the three-dimensional structure and motions of galaxies in the nearby universe.
