How this entity was disambiguated

This entity first appeared as the object of triple T2036077 — 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.

NED1 Entity disambiguation (via context triple) gpt-5-mini-2025-08-07

Target entity: OGLE-III
Context triple: [OGLE, phase, OGLE-III]

A. Cetus Dwarf Galaxy
The Cetus Dwarf Galaxy is a faint, spheroidal dwarf galaxy located in the constellation Cetus and is one of the small satellite members of our cosmic neighborhood.
B. Aquarius Dwarf Galaxy
The Aquarius Dwarf Galaxy is a faint, small dwarf irregular galaxy on the outskirts of the Local Group, notable for its low luminosity and sparse stellar population.
C. Sagittarius Dwarf Spheroidal Galaxy
The Sagittarius Dwarf Spheroidal Galaxy is a small, elongated satellite galaxy currently being tidally disrupted and absorbed by the Milky Way.
D. Canis Major Dwarf Galaxy
The Canis Major Dwarf Galaxy is a nearby, faint irregular dwarf galaxy thought to be the closest known satellite galaxy to the Milky Way and currently being tidally disrupted by it.
E. Carina Dwarf Galaxy
The Carina Dwarf Galaxy is a faint, spheroidal satellite galaxy of the Milky Way located in the Local Group, notable for its low luminosity and predominantly old stellar population.
F. None of above. chosen
G. Unsure - the case is ambiguous/there is not enough information to decide.
