hera_sim.utils.find_baseline_orientations¶

hera_sim.utils.find_baseline_orientations(antenna_numbers: ndarray, enu_antpos: ndarray) → dict[tuple[int, int], float][source]¶

Find the orientation of each redundant baseline group.

Parameters:

antenna_numbers – Array containing antenna numbers corresponding to the provided antenna positions.
enu_antpos – (Nants,3) array containing the antenna positions in a local topocentric frame with basis (east, north, up).

Returns:

antpair2angle – Dictionary mapping antenna pairs (ai,aj) to baseline orientations. Orientations are defined on [0,2pi).
