astropy.modeling.projections.Sky2PixProjection
,astropy.modeling.projections.Zenithal
Zenithal perspective projection - sky to pixel.
Corresponds to the
AZP
projection in FITS WCS.where:
Parameters: mu : float
Distance from point of projection to center of sphere in spherical radii, μ. Default is 0.
gamma : float
Look angle γ in degrees. Default is 0°.
