ellipticDescending function

({double jde, double r}) ellipticDescending(
  1. double axis,
  2. double ecc,
  3. double argP,
  4. double timeP,
)

Time and distance at descending node for an elliptic orbit.

Implementation

({double jde, double r}) ellipticDescending(
    double axis, double ecc, double argP, double timeP) {
  return _el(math.pi - argP, axis, ecc, timeP);
}
