Classifications
Graticule
Meridians: Complex curves without much bend from ~30°–~65°.
Parallels: Curved away from the equator with increasing distance from the central meridian.
Symmetry: About the central meridian and about the equator.
Distortion
Undistorted only at the center of the map.
Distortion is predominately in the form of areal inflation, although a considerable band around the equator, while low in distortion, in dominated by angular deformation.
