/************************************************************************

The TASS 1.7 theory of the Saturnian satellites including HYPERION
by Alain VIENNE and Luc DURIEZ can be found at
ftp://ftp.imcce.fr/pub/ephem/satel/tass17

I (Johannes Gajdosik) have just taken the Fortran code and data
obtained from above and rearranged it into this piece of software.

I can neither allow nor forbid the usage of the TASS 1.7 theory.
The copyright notice below covers not the work of Alain VIENNE and Luc DURIEZ
but just my work, that is the compilation of the TASS 1.7 theory
into the software supplied in this file.
