Description
Astronomy software can calculate positions of celestial bodies and related events with high precision.
This Fortran library is useful for scientific tools, observatory workflows, ephemeris calculations, education software, or simulations that need accurate sky-position routines. It does not provide a planetarium app by itself; another program calls the library with its own inputs and display logic.
Scientific accuracy depends on the models, time data, coordinates, and assumptions used by the parent software.
