Phrase: Besselian epoch | Statement: [Besselian year, epochNotation, Besselian epoch]

Target entity: Besselian epoch
Context triple: [Besselian year, epochNotation, Besselian epoch]

• A. Besselian year chosen
  A Besselian year is a time interval used in astronomy, defined with respect to the Sun’s mean position relative to the stars and historically used as a reference for star catalogs and celestial coordinates.
• B. 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.
• C. Barycentric Dynamical Time
  Barycentric Dynamical Time is a relativistic time scale used in celestial mechanics and ephemerides, defined for an observer at the solar system’s barycenter to accurately model planetary and spacecraft motions.
• D. 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.
• E. Tabulae eclipsium
  Tabulae eclipsium is a 15th-century set of astronomical eclipse tables by Georg von Peuerbach that significantly improved the accuracy of predicting solar and lunar eclipses in late medieval Europe.
• F. None of above.
• G. Unsure - the case is ambiguous/there is not enough information to decide.

Target predicate: epochNotation
Context triple: [Besselian year, epochNotation, Besselian epoch]

• A. timeNotation
  Indicates the specific system or format used to represent and write times (e.g., 12-hour vs 24-hour notation).
• B. epochReference chosen
  Indicates a temporal relationship where one time expression is interpreted relative to a specified reference epoch or baseline time.
• C. calendarEpoch
  Indicates the reference starting point in time from which a particular calendar system counts its dates.
• D. DecEpoch
  Indicates the specific point in time (epoch) at which a declination (Dec) measurement or coordinate value is defined or referenced.
• E. chronographiaCoversPeriodTo
  Indicates that a chronographic work or record extends its coverage up to a specified end point in time.
• F. None of above.
