Spherical Projections
---------------------
Figure 1.14.

Four common full-sky projections. The shaded ellipses represent the distortion
across the sky: each is projected from a circle of radius 10 degrees on the
sphere. The extent to which these are distorted and/or magnified shows the
distortion inherent to the mapping.
