Zenithal perspective projection - sky to pixel.
Corresponds to the
SZP
projection in FITS WCS.Parameters: mu : float
distance from point of projection to center of sphere in spherical radii, μ. Default is 0.
phi0 : float
The longitude φ₀ of the reference point, in degrees. Default is 0°.
theta0 : float
The latitude θ₀ of the reference point, in degrees. Default is 90°.
