Methods

localSiderealTime(double jdTT, {double? deltaTSeconds}) → double
Local apparent sidereal time (radians) at jdTT; deltaTSeconds overrides the ΔT model.
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
position(double jdTT, {double? deltaTSeconds}) → Vector3
Geocentric position of the observer in km, in the frame of the true equator and equinox of date at jdTT.
toString() → String
A string representation of this object.

Operators

operator ==(Object other) → bool
The equality operator.
