Sky2Pix_CylindricalEqualArea¶

class astropy.modeling.projections.Sky2Pix_CylindricalEqualArea(lam=1, **kwargs)[source] [edit on github]¶

Cylindrical equal area projection - sky to pixel.

Corresponds to the CEA projection in FITS WCS.

$x &= \phi \\ y &= \frac{180^{\circ}}{\pi}\frac{\sin \theta}{\lambda}$

Parameters:

lam : float

Radius of the cylinder in spherical radii, λ. Default is 0.
