lenticular

Graticule

Meridians: Central meridian is straight and half the length of the equator. Other meridians are curves, equally spaced along the equator and concave toward the central meridian.
Parallels: Equator is straight. Other parallels are curves, equally spaced along the central meridian and concave toward the nearest pole.
Poles: Curved lines.
Symmetry: About the central meridian and the equator.

Scale

Scale is correct along central meridian and equator.

Distortion

Free of distortion at the intersection of the equator and central meridian. Distortion is low along the equatorial band and central region. Poles are highly distorted but balanced between inflation and angular deformation. Angular deformation dominates the remainder of the map.
