AltAz

class astropy.coordinates.AltAz(*args, **kwargs)

Bases: astropy.coordinates.BaseCoordinateFrame

A coordinate or frame in the Altitude-Azimuth system (i.e., Horizontal coordinates).

Warning

The AltAz class currently does not support any transformations. In a future version, it will support the standard IAU2000 AltAz<->ICRS transformations. It is provided right now as a placeholder for storing as-observed horizontal coordinates.

Parameters:

representation : BaseRepresentation or None

A representation object or None to have no data (or use the other keywords)

az : Angle, optional, must be keyword

The Azimuth for this object (alt must also be given and representation must be None).

alt : Angle, optional, must be keyword

The Altitude for this object (az must also be given and representation must be None).

distance : Quantity, optional, must be keyword

The Distance for this object along the line-of-sight.
