Properties

`Readonly`ayanamsa

ayanamsa: string

The definition's name.

`Readonly`deltaT

deltaT: DeltaT

The ΔT (TT − UT1) the instant was read with: its time basis's, or the pin.

`Readonly`flags

flags: readonly "outside-reference-span"[]

"outside-reference-span" when the instant, or an epoch definition's epoch, is outside REFERENCE_SPAN.

`Readonly`julianDateTT

julianDateTT: number

`Readonly`mean

mean: number

Referred to the mean equinox and ecliptic of date, in (−180, 180].

`Readonly`nutation

nutation: number

The engine's nutation in longitude Δψ.

`Readonly`timeScale

timeScale: TimeScale

How the instant became UT1 and TT, as a chart's timeScale (docs/time.md).

`Readonly`true

true: number

mean + nutation: subtract it from the engine's tropical longitudes.

`Readonly`utc

utc: string

The instant as given, ISO 8601, on the scale timeScale.input names (UTC unless the options say otherwise), named as ChartInput.utc is: on UT1 or TT input it is that reading, with a Z. A SiderealLongitude made from this value has the UTC instant of the time basis in its own utc.
