class astropy.modeling.projections.Sky2Pix_CYP[source] [edit on github]¶

CYP : Cylindrical Perspective - sky to pixel.

$x &= \lambda \phi \\ y &= \frac{180^{\circ}}{\pi}\left(\frac{\mu + \lambda}{\mu + \cos \theta}\right)\sin \theta$

Parameters:

mu : float

distance from center of sphere in the direction opposite the projected surface, in spherical radii, default is 0.

lam : float

radius of the cylinder in spherical radii, default is 0.
