> far < gives distance of the body from the Earth (in Earth radii for Moon),
> L-LS < difference of the ecliptical longitude of the body
from that of the Sun (if positive, the body is east from the Sun),
> old < for Moon is (L-LS / 360 degrees) * 29.53059 days
> Illu.< horizontal direct illumination by the object
> b < planetographic latitude of the subterrestrial point
> PA < position angle of the central meridian of the planet
> long < planetographic longitude of the subterrestrial point
> PhA < "phase angle", i.e., angle Sun-body-Earth.
> col. < for Moon is the so-called colongitudo (its PhA=abs(L-LS))
