CAAAberration_EquatorialAberration: CAAAberration_EquatorialAberration

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

Description

CAAAberration_EquatorialAberration

Usage

CAAAberration_EquatorialAberration(Alpha, Delta, JD)

Arguments

Alpha	Alpha The right ascension expressed as an hour angle.
Delta	Delta The declination in degrees.
JD	JD The date in Dynamical time to calculate for.

Value

Returns the correction due to aberration. The X value will contain the right ascension correction expressed as an hour angle and Y will contain the declination correction in degrees.
