Target class: high-precision radial-velocity instrument Context triple: [SPIRou, instanceOf, high-precision radial-velocity instrument]
-
A.
radial velocity measurement method
A radial velocity measurement method is a technique used to determine the component of an object's velocity along the line of sight, typically by analyzing Doppler shifts in its spectral lines.
-
B.
astronomical spectrograph
chosen
An astronomical spectrograph is an instrument that disperses light from celestial objects into its component wavelengths to measure their physical properties, such as composition, temperature, velocity, and redshift.
-
C.
optical echellette spectrograph
An optical echellette spectrograph is a medium- to high-resolution astronomical instrument that disperses incoming light into a cross-dispersed spectrum using an echelle grating operated at relatively low orders, enabling broad wavelength coverage in a compact format.
-
D.
near-infrared spectrograph
A near-infrared spectrograph is an instrument that disperses and measures light in the near-infrared wavelength range to analyze the composition, temperature, and other properties of astronomical or laboratory targets.
-
E.
spectrograph
A spectrograph is an instrument that disperses incoming light or other electromagnetic radiation into its component wavelengths to record and analyze their spectrum.
- F. None of above.
Provenance (1 batch)
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.
