How this entity was disambiguated

This entity first appeared as the object of triple T2139150 — 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: Imaging IR Spectrometer
Context triple: [Chandrayaan-2, instrumentsOnOrbiter, Imaging IR Spectrometer]

A. Mid-Infrared Instrument
The Mid-Infrared Instrument (MIRI) is a key James Webb Space Telescope payload that provides imaging, spectroscopy, and coronagraphy in the mid-infrared range to study cold, distant, and dust-obscured cosmic objects.
B. Fourier transform spectrometer
A Fourier transform spectrometer is an optical instrument that measures the spectrum of a light source by recording an interference pattern and mathematically transforming it to obtain high-resolution spectral information.
C. Near Infrared Imager and Slitless Spectrograph
The Near Infrared Imager and Slitless Spectrograph (NIRISS) is a James Webb Space Telescope instrument designed for high-sensitivity near-infrared imaging and spectroscopy, particularly suited for exoplanet characterization and studies of distant galaxies.
D. MMIRS (Magellan/MMT Infrared Spectrograph)
MMIRS (Magellan/MMT Infrared Spectrograph) is a near-infrared imaging spectrograph designed for the Magellan and MMT telescopes to study faint astronomical objects at infrared wavelengths.
E. NIRSpec
NIRSpec is a powerful near-infrared spectrograph on the James Webb Space Telescope designed to analyze the light from distant astronomical objects to study their composition, motion, and physical properties.
F. None of above. chosen
G. Unsure - the case is ambiguous/there is not enough information to decide.
