In addition to plotting the Moon curve fix computed yesterday, I also plot the four other LOPs from Frank's set (attached PNG, using Kermit's scale of 1 cm representing 1 NM).
In the following, each LOP is characterized by intercept and azimuth, but also by its intersections with the AP's latitude and longitude. Since in this case all LOPs run in sufficiently oblique directions, they can be plotted directly using these intersection points.
