TA: Horizontal slices through the common volume at about 120 km altitude.
In the top panel, the curves are contours of the quantity Γ, defined in
Eq. (96), at the nominal beam intersection altitude. The bottom panel gives
the effective are, defined in Eq. (97), as a function of altitude. The plot was
produced by common volume.m.
