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: Besselian elements | Statement: [Friedrich Bessel, notableFor, Besselian elements]

Target entity: Besselian elements
Context triple: [Friedrich Bessel, notableFor, Besselian elements]

• A. Saros cycle
  The Saros cycle is an approximately 18-year period after which nearly identical solar and lunar eclipses repeat, due to the alignment of the Earth, Moon, and Sun.
• B. Newcomb tables of the Sun, Mercury, Venus, and Mars
  The Newcomb tables of the Sun, Mercury, Venus, and Mars are a set of highly accurate 19th-century astronomical tables computed by Simon Newcomb that were long used to predict the positions and motions of these celestial bodies.
• C. Keplerian orbital elements
  Keplerian orbital elements are a set of parameters that uniquely describe the size, shape, and orientation of an orbit and the position of an orbiting body along that path.
• D. Ephemerides
  Ephemerides is a 15th-century astronomical table compiled by Regiomontanus that provided highly accurate planetary positions and became a foundational tool for navigation and astronomy in early modern Europe.
• E. Occultation
  Occultation is a central Twelver Shia belief that the twelfth Imam, Muhammad al-Mahdi, is alive but hidden from public view and will reappear at the end of times to establish justice.
• F. None of above. chosen
• G. Unsure - the case is ambiguous/there is not enough information to decide.

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: Besselian elements
Triple: [Friedrich Bessel, notableFor, Besselian elements]

Besselian elements are mathematical parameters introduced by Friedrich Bessel that precisely describe the geometry and timing of a solar eclipse as seen from Earth.
