Target entity: standard reference for European astronomers before Copernicus
Context triple: [Alfonsine Tables, historicalSignificance, standard reference for European astronomers before Copernicus]

• A. Tycho Brahe’s star catalogue
  Tycho Brahe’s star catalogue is a pioneering late 16th-century astronomical compilation renowned for its unprecedented positional accuracy and for laying the observational foundation for Kepler’s laws of planetary motion.
• B. Fundamenta Astronomiae
  Fundamenta Astronomiae is a foundational 19th-century astronomical catalog by Friedrich Bessel that provided highly accurate star positions and proper motions, significantly advancing astrometry.
• C. Copernican period
  The Copernican period is the most recent era in the Moon’s geological timescale, characterized by relatively young, bright craters with well-preserved ray systems.
• D. Epitome Astronomiae Copernicanae
  Epitome Astronomiae Copernicanae is Johannes Kepler’s influential early-17th-century astronomy textbook that systematically presented and expanded Copernican heliocentrism using Kepler’s own laws of planetary motion.
• E. Histoire de l’astronomie ancienne
  Histoire de l’astronomie ancienne is an 18th-century historical study of ancient astronomy by French astronomer and writer Jean-Sylvain Bailly, examining the origins and development of astronomical knowledge in early civilizations.
• F. None of above. chosen
• G. Unsure - the case is ambiguous/there is not enough information to decide.

Target entity: standard reference for European astronomers before Copernicus
Target entity description: The Alfonsine Tables were a 13th-century set of astronomical tables, commissioned by King Alfonso X of Castile, that provided planetary positions and became the principal computational tool for European astronomers until the Copernican revolution.
