com.ibm.icu.impl.CalendarAstronomer.Equatorial
- Enclosing class:
CalendarAstronomer
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.
