Target class: astronomical time standard Context triple: [Ephemeris Time, instanceOf, astronomical time standard]
-
A.
astrometric standard
An astrometric standard is a celestial object with precisely known position and motion used as a reference to calibrate and validate astrometric measurements.
-
B.
astronomical reference parameter
chosen
An astronomical reference parameter is a standardized value or constant used to define, calibrate, or relate measurements in astronomy, such as positions, motions, or physical properties of celestial objects, within a chosen reference frame or system.
-
C.
astronomical cycle
An astronomical cycle is a recurring, measurable pattern in the motions or configurations of celestial bodies, such as orbits, rotations, or alignments, that repeats over a characteristic period.
-
D.
astronomical chronicle
An astronomical chronicle is a systematic record of celestial events and observations, often organized by date, that documents phenomena such as planetary motions, eclipses, comets, and stellar occurrences over time.
-
E.
atomic clock
An atomic clock is an extremely precise timekeeping device that measures time based on the natural vibration frequencies of atoms, typically cesium or rubidium.
- 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.
