-
A.
Chandra High Resolution Mirror Assembly
chosen
The Chandra High Resolution Mirror Assembly is the precision X-ray telescope optics system on NASA’s Chandra X-ray Observatory, designed to focus high-energy X-rays with exceptionally fine angular resolution for astrophysical observations.
-
B.
Stanford normal-incidence X-ray telescope experiments
The Stanford normal-incidence X-ray telescope experiments were pioneering solar physics projects that used advanced multilayer-coated optics to obtain high-resolution images of the Sun in soft X-ray and extreme ultraviolet wavelengths.
-
C.
Wolter type I grazing-incidence telescope
A Wolter type I grazing-incidence telescope is a specialized X-ray imaging system that uses nested, shallowly angled mirror surfaces to focus high-energy X-ray photons that would otherwise penetrate or be absorbed by conventional optical mirrors.
-
D.
X-Ray Telescope
The X-Ray Telescope is a space-based instrument designed to detect and image high-energy X-ray emissions from cosmic sources such as black holes, neutron stars, and gamma-ray bursts.
-
E.
High Energy Transmission Grating Spectrometer
The High Energy Transmission Grating Spectrometer is a high-resolution X-ray spectrometer aboard NASA’s Chandra X-ray Observatory, designed to disperse incoming X-rays into detailed spectra for precise studies of high-energy astrophysical sources.
- F. None of above.
- G. Unsure - the case is ambiguous/there is not enough information to decide.
Provenance (3 batches)
The batch behind each pipeline step, in order, with when it ran. Timestamps are batch-level — stages were processed in waves, so the object chain (NER → NED1 → NEDg → NED2) reads in order, but predicate / elicitation batches can sit in a different wave.
