The functions parameters are:
gjd - geocentric JD based on UTC
ra - right ascension (J2000)
de - declination The function returns heliocentric correction helcor. Using helcor, you can computed Heliocentric JD from Geocentric JD. The relation is: HJD = GJD + helcor.
We do not compute Barycentric JD (BJD).
