The algorithms this server computes from are from:

  Jean Meeus, "Astronomical Algorithms", 2nd edition, Willmann-Bell, 1998.
  Chapters 7 (Julian Day), 11 (the Earth's figure), 12 (sidereal time),
  22 (nutation and obliquity), 40 (parallax) and 47 (the moon's position).

The implementation is ours and is covered by the licence above. The
mathematics is Meeus's and is not claimed. Each chapter is cited in the source
at the point it is used.

Test fixtures under tests/ are recorded responses from NASA JPL's Horizons
system (https://ssd.jpl.nasa.gov/horizons/), used to check this server's
arithmetic. They are facts about the solar system, produced by a US government
service, and are not claimed either.
