# Sky2Pix_Molleweide

class astropy.modeling.projections.Sky2Pix_Molleweide(*args, **kwargs)

  Bases: `Sky2PixProjection`, `PseudoCylindrical`

  Molleweide’s projection - sky to pixel.

  Corresponds to the `MOL` projection in FITS WCS.

  \[\begin{split}x &= \frac{2 \sqrt{2}}{\pi} \phi \cos \gamma \\ y &= \sqrt{2} \frac{180^\circ}{\pi} \sin \gamma\end{split}\]

  where \(\gamma\) is defined as the solution of the transcendental equation:

  \[\sin \theta = \frac{\gamma}{90^\circ} + \frac{\sin 2 \gamma}{\pi}\]
