I release all of my work in this project to the public domain.
Note, though, not everything here can be considered my work. The VSOP87 theory is the work of Bureau des Longitudes. https://site.bdlg.fr/
Other algorithms have been implementated following the equations described in
- Jean Meeus : Astronomical Algorithms Second Edition
- James L. Hilton : Computing Apparent Planetary Magnitudes for The Astronomical Almanac
- George H. Kaplan : The IAU Resolutions on Astronomical Reference Systems, Time Scales, and Earth Rotation Models
