pub fn look_angle_batch_parallel(
satellites: &[Satellite],
ground_station: GroundStation,
datetimes: &[UtcInstant],
) -> Vec<Result<Vec<LookAngle>, LookAngleError>>Expand description
Topocentric look angles for many already-initialized SGP4 satellites over a shared epoch grid, fanned across a rayon thread pool.
Each satellite’s arc is computed by the same serial look_angle_arc kernel
and the indexed parallel collect preserves input order, so element i is
byte-for-byte identical to element i of look_angle_batch_serial.
