CAACoordinateTransformation_Ecliptic2Equatorial: CAACoordinateTransformation_Ecliptic2Equatorial

In helixcn/skycalc: Computational Astronomy in R based on PJ Naughter's AA+ library

Description

CAACoordinateTransformation_Ecliptic2Equatorial

Usage

CAACoordinateTransformation_Ecliptic2Equatorial(Lambda, Beta, Epsilon)

Arguments

Lambda	Lambda The ecliptic longitude in degrees.
Beta	Beta The ecliptic latitude in degrees.
Epsilon	Epsilon the obliquity of the ecliptic in degrees.

Value

Returns the converted equatorial coordinates in a CAA2DCoordinate class. The x value in the class corresponds to the equatorial longitude in hours and the y value corresponds to the equatorial latitude in degrees.
