Sky2Pix_SlantZenithalPerspective

class astropy.modeling.projections.Sky2Pix_SlantZenithalPerspective(mu=0.0, phi0=0.0, theta0=0.0, **kwargs)[source]

Bases: astropy.modeling.projections.Sky2PixProjection, astropy.modeling.projections.Zenithal

Zenithal perspective projection - sky to pixel.

Corresponds to the SZP projection in FITS WCS.

Parameters
mufloat

distance from point of projection to center of sphere in spherical radii, μ. Default is 0.

phi0float

The longitude φ₀ of the reference point, in degrees. Default is 0°.

theta0float

The latitude θ₀ of the reference point, in degrees. Default is 90°.
