GeocentricSolarEcliptic#

class sunpy.coordinates.GeocentricSolarEcliptic(*args, **kwargs)[source]#

A coordinate or frame in the Geocentric Solar Ecliptic (GSE) system.

The origin is the center of the Earth.
The X-axis (0 degrees longitude and 0 degrees latitude) is aligned with the Earth-Sun line.
The Z-axis (+90 degrees latitude) is aligned with the component perpendicular to the X-axis of the mean ecliptic pole at the observation time.

Parameters:

data (BaseRepresentation or None) – A representation object or None to have no data (or use the coordinate component arguments, see below).
lon (Angle or Quantity, optional) – The longitude coordinate for this object (lat must also be given and data must be None). Not needed if data is given.
lat (Angle or Quantity, optional) – The latitude coordinate for this object (lon must also be given and data must be None). Not needed if data is given.
distance (Quantity, optional) – The distance coordinate from Earth center for this object. Not needed if data is given.
obstime (tuple, list, str, pandas.Timestamp, pandas.Index, pandas.Series, pandas.DatetimeIndex, datetime.datetime, datetime.date, numpy.datetime64, numpy.ndarray, astropy.time.Time) – The time of the observation. This is used to determine the position of solar-system bodies (e.g., the Sun and the Earth) as needed to define the origin and orientation of the frame.
representation_type (BaseRepresentation, str, optional) – A representation class or string name of a representation class. This may change the valid coordinate component arguments from the defaults (see above). For example, passing representation_type='cartesian' will make the frame expect Cartesian coordinate component arguments (typically, x, y, and z).
copy (bool, optional) – If True (default), make copies of the input coordinate arrays.

Notes

Aberration due to Earth motion is not included when transforming directly to/from this frame.
