Detailed Description

A BoundedField that gives the amount a pixel is distorted at each point.

This is ratio of the SkyWcs-transformed pixel area to the transformed pixel area at the SkyWcs center, or equivalently the determinant of the Jacobian of the SkyWcs Transform.

Typically used to move an image or source flux between surface brightness and fluence space.
