API Reference / syntheticEphemeris · function
Function: syntheticEphemeris()
function syntheticEphemeris(sys): BodyPositionSource;
A BodyPositionSource over an authored system: the world-frame view as
a reusable object, with longitude speed and a retrograde flag so it satisfies
the same contract real ephemeris bodies do. Carries the system's
validateSyntheticSystem diagnosis (impossible/problems) — the
honesty pattern — and still serves the bodies that are individually valid.
Parameters
| Parameter | Type | Description |
|---|---|---|
sys | SyntheticSystem | The authored system. |
Returns
A position source: bodies(), longitude(id, t), position(id, t),
plus impossible/problems.
