Kapteyn Selected Areas survey

Target entity: Kapteyn Selected Areas survey
Context triple: [Jacobus Cornelius Kapteyn, notableWork, Kapteyn Selected Areas survey]

• A. Cape Photographic Durchmusterung
  The Cape Photographic Durchmusterung is a major late-19th-century photographic star catalog that systematically surveyed the southern sky and significantly expanded knowledge of southern hemisphere stars.
• B. Palomar Observatory Sky Survey
  The Palomar Observatory Sky Survey is a landmark mid-20th-century photographic mapping of the night sky that produced some of the most widely used astronomical reference images for research and discovery.
• C. Garching-Bonn Deep Survey
  The Garching-Bonn Deep Survey is an astronomical deep-imaging project designed to study distant galaxies and large-scale cosmic structures using wide-field observations.
• D. VISTA Hemisphere Survey
  The VISTA Hemisphere Survey is a large-scale near-infrared sky survey using the VISTA telescope to map the entire southern celestial hemisphere for studies of Galactic structure, nearby stars, and distant galaxies.
• E. Carte du Ciel project
  The Carte du Ciel project was a late 19th- and early 20th-century international astronomical initiative to create a comprehensive photographic map and catalog of the entire night sky.
• F. None of above. chosen
• G. Unsure - the case is ambiguous/there is not enough information to decide.

Target entity: Kapteyn Selected Areas survey
Target entity description: The Kapteyn Selected Areas survey is an early 20th-century astronomical project that systematically mapped and studied the distribution and motions of stars in carefully chosen regions of the sky to investigate the structure of the Milky Way.
