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

a_radius

double semimajor axis of the ellipsoid that defines the approximate shape of a target body used in projection (m).

b_radius

double intermediate axis of the ellipsoid that defines the approximate shape of a target body used in projection (m).

bdis_obs

double Distance between the centre of the celestial body and the observer (m).

blat_obs

double Bodycentric latitude of the observer in the body-fixed reference frame of the target body (deg).

blon_obs

double Bodycentric longitude of the observer in the body-fixed reference frame of the target body, spanning from 0 to 360 deg (deg).

c_radius

double semiminor axis of the ellipsoid that defines the approximate shape of a target body used in projection (m).

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).
