HeliocentricEarthEcliptic

class heliopy.coordinates.frames.HeliocentricEarthEcliptic(*args, copy=True, representation_type=None, differential_type=None, **kwargs)

Bases: astropy.coordinates.baseframe.BaseCoordinateFrame

A coordinate frame in the Heliocentric Earth Ecliptic (HEE) system.

Possible call signatures:

hee = HeliocentricEarthEcliptic(x, y, z)
hee = HeliocentricEarthEcliptic(x, y, z, obstime=obstime)

The x-y plane is the Earth mean ecliptic, the x-axis points from the Sun to the Earth, and the z-axis points North out of the ecliptic plane.

Parameters:
  • x (Quantity) – x-coordinate(s)
  • y (Quantity) – y-coordinate(s)
  • z (Quantity) – z-coordinate(s)
  • obstime (datetime, optional) – Observation time. Required for some transformations between different coordinate systems.
