<a id="aspects"></a> aspects | Aspect[] | Aspects found among the bodies, within the active orbs. |
<a id="bodies"></a> bodies | ChartBodies | Apparent position per body, enriched with house and dignities, keyed by body id. See ChartBody. |
<a id="cusps"></a> cusps | number[] | The twelve house cusp longitudes in degrees, house 1 first. |
<a id="housesystem"></a> houseSystem | HouseSystem | House system actually used. May differ from the request: Placidus and Koch are undefined above the polar circles and fall back to whole_sign. |
<a id="housesystemrequested"></a> houseSystemRequested | HouseSystem | The house system originally requested, before any polar fallback. |
<a id="jdut"></a> jdUt | number | The instant, as a Julian Day (UT). |
<a id="unavailable"></a> unavailable | string[] | Body ids that were requested but omitted because the instant falls outside their fitted range (e.g. Chiron and other Chebyshev-packed bodies before ~1850 or after ~2150). Empty for the usual modern dates. The analytic bodies (Sun through Neptune and the nodes) are always present. |
<a id="warnings"></a> warnings | ChartWarning[] | Validity statements about this chart: bodies computed outside their measured validated span, and the delta-T uncertainty at historical epochs. Empty for the usual modern dates. The chart still computes -- these are data, not errors -- but a consumer must not present a warned position as validated. |
<a id="zodiac"></a> zodiac | Zodiac | The zodiac the longitudes are expressed in. |
