How this entity was disambiguated

This entity first appeared as the object of triple T4148489 — resolving that mention is where its identity was fixed. The disambiguator weighed these candidate entities and picked the highlighted one (or “None”, minting a new entity). This is how homonymy is resolved: the same surface form can point to different entities.

Target entity: Planck 2018 results
Context triple: [Planck spacecraft, dataRelease, Planck 2018 results]

A. Planck 2013 results
Planck 2013 results is the first major cosmological data release from the Planck mission, providing high-precision measurements of the cosmic microwave background that refined key parameters of the standard model of cosmology.
B. ESA Planck Legacy Archive
The ESA Planck Legacy Archive is the official repository providing public access to the full mission data and scientific products from the Planck cosmic microwave background observatory.
C. Planck
Planck is a German theoretical physicist renowned as the founder of quantum theory and a Nobel Prize laureate in Physics.
D. Planck spacecraft
The Planck spacecraft was a European Space Agency space observatory designed to study the cosmic microwave background radiation with unprecedented precision to improve our understanding of the early universe and cosmology.
E. WMAP
WMAP (Wilkinson Microwave Anisotropy Probe) was a NASA space observatory that precisely mapped the cosmic microwave background radiation, revolutionizing our understanding of the universe’s age, composition, and development.
F. None of above. chosen
G. Unsure - the case is ambiguous/there is not enough information to decide.
