Pix2Sky_Airy

class astropy.modeling.projections.Pix2Sky_Airy(theta_b=90.0, **kwargs)[source] [edit on github]

Bases: astropy.modeling.projections.Pix2SkyProjection, astropy.modeling.projections.Zenithal

Airy projection - pixel to sky.

Corresponds to the AIR projection in FITS WCS.

See Zenithal for a definition of the full transformation.

Parameters:

theta_b : float

The latitude \(\theta_b\) at which to minimize the error, in degrees. Default is 90°.
