Class CalendarAstronomer.Equatorial

java.lang.Object

org.graalvm.shadowed.com.ibm.icu.impl.CalendarAstronomer.Equatorial

Enclosing class:

CalendarAstronomer

public static final class CalendarAstronomer.Equatorial
extends Object

Represents the position of an object in the sky relative to the plane of the earth's equator. The Right Ascension specifies the position east or west along the equator, relative to the sun's position at the vernal equinox. The Declination is the position north or south of the equatorial plane.

Note that Equatorial objects are immutable and cannot be modified once they are constructed. This allows them to be passed and returned by value without worrying about whether other code will modify them.

Field Detail

ascension

public final double ascension

The right ascension, in radians. This is the position east or west along the equator relative to the sun's position at the vernal equinox, with positive angles representing East.

declination

public final double declination

The declination, in radians. This is the position north or south of the equatorial plane, with positive angles representing north.
