Bases: astropy.coordinates.BaseCoordinateFrame
Barycentric ecliptic coordinates. These origin of the coordinates are the barycenter of the solar system, with the x axis pointing in the direction of the true (not mean) equinox as at the time specified by the equinox attribute (as seen from Earth), and the xy-plane in the plane of the ecliptic for that date.
This frame has one frame attribute:
The date to assume for this frame. Determines the location of the x-axis and the location of the Earth and Sun.
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!)
