CAAFK5_ConvertVSOPToFK5AnyEquinox: CAAFK5_ConvertVSOPToFK5AnyEquinox

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

Description

CAAFK5_ConvertVSOPToFK5AnyEquinox

Usage

CAAFK5_ConvertVSOPToFK5AnyEquinox(value_X, value_Y, value_Z, JDEquinox)

Arguments

value_X	value X The geometric rectangular ecliptical coordinates of the object (e.g. the Sun) to convert from the dynamical reference frame (VSOP) to the equatorial FK5 reference frame of JDEquinox.
value_Y	value Y The geometric rectangular ecliptical coordinates of the object (e.g. the Sun) to convert from the dynamical reference frame (VSOP) to the equatorial FK5 reference frame of JDEquinox.
value_Z	value Z The geometric rectangular ecliptical coordinates of the object (e.g. the Sun) to convert from the dynamical reference frame (VSOP) to the equatorial FK5 reference frame of JDEquinox.
JDEquinox	The Julian day for which equatorial coordinates should be calculated for.

Value

A class containing the converted equatorial FK5 reference frame coordinates.
