This function returns the cosine of the maximum field angle, i.e., the maximum angular distance from ...
Projection type() const override
Return the type of this projection.
double radius() const override
Get the radius of this projection's sky circle.
double projectionL(double x) const override
This function handles some of the projection-specific code.
double projectionK(double x) const override
This function handles some of the projection-specific code.
This is just a container that holds information needed to do projections.
