# Auxprm¶

class astropy.wcs.Auxprm

Bases: object

Class that contains auxiliary coordinate system information of a specialist nature.

This class can not be constructed directly from Python, but instead is returned from aux.

Attributes Summary

 crln_obs double Carrington heliographic longitude of the observer (deg). dsun_obs double Distance between the centre of the Sun and the observer (m). hgln_obs double Stonyhurst heliographic longitude of the observer. hglt_obs double Heliographic latitude (Carrington or Stonyhurst) of the observer (deg). rsun_ref double Reference radius of the Sun used in coordinate calculations (m).
