- nyx.core.coordinates.offset_to_altaz(lon, lat, rotation)[source]¶
Transform offset frame (lon, lat) to AltAz; inverse of
altaz_to_offset().- Parameters:
lon (array-like) – Offset frame coordinates in radians.
lat (array-like) – Offset frame coordinates in radians.
rotation (array-like, shape (3, 3)) – Rotation matrix from
rotation_matrix_from_altaz().
- Returns:
az, alt – AltAz coordinates in radians.
- Return type:
