Astronomical Algorithms, Tables of Meeus

[Klaus]

Years ago I wrote a program on the HP50 that uses the Meeus shortened VSOP. Running time, for example for Venus ~2.5 min
Later, with NewRPL for the HP50, a program with the complete VSOP theory.
Running time, e.g. for Venus under 1 min
Programs are not mature and can still be optimized and run with an inserted SD card.
