swiss-ephemeris v1.1.0.0 Release Notes

Release Date: 2020-09-12 // over 3 years ago

  • BREAKING CHANGE: the Coordinates type has been retired, in favor of the more specific
    GeographicPosition and EclipticPosition. calculateCoordinates is now calculateEclipticPosition,
    and the calculateCusps* family now takes a GeographicPosition as part of its inputs.

    • Introduces an Internal module with types and helpers that this library introduces,
      which are not native to the underlying C library. Import at your own risk! (the "curated"/
      "stable" ones are re-exported by the main module.)
      • Deprecates the Coordinates type, in favor of EclipticPosition.
    • Introduces functions to calculateEquatorialPosition and calculteObliquity at a given time,
      👍 as well as types that better convey the different types of positions (EquatorialPosition, ObliquityInformation).
    • Some astrology helpers: convert between equatorial and ecliptic (and vice-versa,)
      obtain the Delta Time effective at a given moment, obtain the house position of a given body.
      ( Note: the calculateHousePosition function is more useful for working near the polar circles or for bodies
      off of the ecliptic -- the ARMC and obliquity need to be calculated or provided, it's simpler
      if you already have the cusps: just check which cusps a given longitude falls between -- no need for
      this function!)
