ASTRO-C
ASTRONOMY COMPUTATIONS
ASTRO-C allows you to solve numerous
computational problems in advanced
astronomy. It is a powerful tool for amateurs
and professional scientists, yet it is very easy
to use. ASTRO-C is a library of menu selected
programs that are compiled versions of
spreadsheet templates. Having the "feel" of
a spreadsheet, the programs facilitate "what if"
calculations and unambiguous data entry, but
without requiring a spreadsheet program to run.
Standard graphical and tabular displays are
provided. However, these can be customized by
the user.
A comprehensive user's manual provides
examples, detailed descriptions of the
mathematical formulae and techniques used
in all the calculations, and references.
The programs are based on the algorithms and
formulae in Meeus' "Astronomical Formulae for
Calculators", Zombeck's "Handbook of Space
Astronomy and Astrophysics" and the Nautical
Almanac.
