class
astropy.modeling.projections.Pix2Sky_CylindricalEqualArea(lam=1, **kwargs)[source] [edit on github]¶ Bases:
astropy.modeling.projections.Pix2SkyProjection,astropy.modeling.projections.CylindricalCylindrical equal area projection - pixel to sky.
Corresponds to the
CEAprojection in FITS WCS.\[\begin{split}\phi &= x \\ \theta &= \sin^{-1}\left(\frac{\pi}{180^{\circ}}\lambda y\right)\end{split}\]Parameters: - lam : float
Radius of the cylinder in spherical radii, λ. Default is 0.
