Xplanet 0.43
Dec 06 1999

Most of the algorithms are taken from "Astronomical Formulae for
Calculators" by Jean Meeus, published by Willman-Bell.  The rotational
parameters for the other terrestrial planets are taken from "Practical
Ephemeris Calculations" by Oliver Montenbruck, published by
Springer-Verlag.  Rotational parameters for the Moon are taken from
Davies et al. (1996), Celestial Mechanics 63, 127--148.

Thanks to ...

the maps for my web page.

Henri Simoes for the french translation of the man page.

Per Erik Stendahl and Larry Reeder for catching a bug in

segfaults.

properly if --center was specified.
