Constructor Details

#initialize(instant:, target_astrometric_position:, ephem:) ⇒ Deflection

Returns a new instance of Deflection.

Parameters:

  • instant (Astronoby::Instant) —

    the instant of the observation

  • target_astrometric_position (Astronoby::Vector<Distance>) —

    the astrometric position of the target

  • ephem (Astronoby::Ephemeris) —

    the ephemeris to use for the computation
