  • flipped (bool, optional) – If True, the azimuthal axis is flipped, following equatorial convention

  • frame (str, optional) – Either ‘equatorial’, ‘galactic’, or ‘spacecraft’. Default is ‘equatorial’

  • face_color (str, optional) – The color of the circle fill

  • face_alpha (float, optional) – The alpha of the circle fill

  • edge_color (str, optional) – The color of the circle edge

  • edge_alpha (float, optional) – The alpha of the circle edge

  • **kwargs – Other plotting options

Returns:
