Pix2Sky_SlantZenithalPerspective
(mu=0.0, phi0=0.0, theta0=90.0, **kwargs)[source] [edit on github]¶ Bases:
astropy.modeling.projections.Pix2SkyProjection
,astropy.modeling.projections.Zenithal
Slant zenithal perspective projection - pixel to sky.
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°.
