class
astropy.modeling.projections.Pix2Sky_Molleweide(*args, meta=None, name=None, **kwargs)[source] [edit on github]¶ Bases:
astropy.modeling.projections.Pix2SkyProjection,astropy.modeling.projections.PseudoCylindricalMolleweide’s projection - pixel to sky.
Corresponds to the
MOLprojection in FITS WCS.\[\begin{split}\phi &= \frac{\pi x}{2 \sqrt{2 - \left(\frac{\pi}{180^\circ}y\right)^2}} \\ \theta &= \sin^{-1}\left(\frac{1}{90^\circ}\sin^{-1}\left(\frac{\pi}{180^\circ}\frac{y}{\sqrt{2}}\right) + \frac{y}{180^\circ}\sqrt{2 - \left(\frac{\pi}{180^\circ}y\right)^2}\right)\end{split}\]Methods Summary
