If you really want to see the equations, e-mail me. They're ugly.
For a field at the latitude of 52 degrees:
If the field is 1/2 mile E-W and 1/4 mile N-S, the AB lines will diverge by 1.28 inches.
If the field is 1/4 mile E-W and 1/2 mile N-S, the AB lines will diverge by 5.12 inches.
If the field is 1 mile square, the AB lines will diverge by 20.5 inches.
