BaseMagnetic#
- class sunpy.coordinates.frames.BaseMagnetic(*args, **kwargs)[source]#
Bases:
SunPyBaseCoordinateFrame
Base class for frames that rely on the Earth’s magnetic model (MAG, SM, and GSM).
This class is not intended to be used directly and has no transformations defined.
Attributes Summary
Default representation for differential data (e.g., velocity)
Default representation for position data
The geographic longitude/latitude of the Earth's magnetic north pole.
The Earth's dipole moment.
Mapping for frame-specific component names
A frame attribute

- default_representation#
Default representation for position data
- dipole_lonlat#
The geographic longitude/latitude of the Earth’s magnetic north pole.
This position is calculated from the first three coefficients of the selected IGRF model per Franz & Harper (2002). The small offset between dipole center and Earth center is ignored.
