RepresentationMapping

class astropy.coordinates.RepresentationMapping(reprname: str, framename: str, defaultunit: str | Unit = 'recommended')

Bases: NamedTuple

This NamedTuple is used with the frame_specific_representation_info attribute to tell frames what attribute names (and default units) to use for a particular representation. reprname and framename should be strings, while defaultunit can be either an astropy unit, the string 'recommended' (which is degrees for Angles, nothing otherwise), or None (to indicate that no unit mapping should be done).
