(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°.
