BaseEclipticFrame

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

Bases: astropy.coordinates.BaseCoordinateFrame

A base class for frames that have names and conventions like that of ecliptic frames.

Warning

In the current version of astropy, the ecliptic frames do not yet have stringent accuracy tests. We recommend you test to “known-good” cases to ensure this frames are what you are looking for. (and then ideally you would contribute these tests to Astropy!)

Parameters:

representation : BaseRepresentation or None

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

lon : Angle, optional, must be keyword

The ecliptic longitude for this object (lat must also be given and representation must be None).

lat : Angle, optional, must be keyword

The ecliptic latitude for this object (lon must also be given and representation must be None).

distance : Quantity, optional, must be keyword

The distance for this object from the {0}. (representation must be None).

pm_lon_coslat : Angle, optional, must be keyword

The proper motion in the ecliptic longitude (including the cos(lat) factor) for this object (pm_lat must also be given).

pm_lat : Angle, optional, must be keyword

The proper motion in the ecliptic latitude for this object (pm_lon_coslat must also be given).

distance : Quantity, optional, must be keyword

The distance for this object from the {0}. (representation must be None).

copy : bool, optional

If True (default), make copies of the input coordinate arrays. Can only be passed in as a keyword argument.
