class astropy.modeling.projections.Pix2Sky_ZenithalEqualArea(*args, **kwargs)

  Bases: `Pix2SkyProjection`, `Zenithal`

  Zenithal equidistant projection - pixel to sky.

  Corresponds to the `ZEA` projection in FITS WCS.

  See `Zenithal` for a definition of the full transformation.

  \[\theta = 90^\circ - 2 \sin^{-1} \left(\frac{\pi R_\theta}{360^\circ}\right)\]
