I like it.
Seems to be alot of pouching of graphics in aerodynamic.
I found this one in the: Alternative approaches to rear end drag reduction
Technical Report, Torbjörn Gustavsson, Stockholm 2006
I believe that it's one of his papers which goes into the shortcomings of NASA's boat-tail, and that of the entire tail structure of the Lockheed C-130 Hercules.

And since the Continuum Dynamics project was tested at NASA Ames, that graphic you posted may be associated with that very research.
With a full belly pan, level with the bottom of the rear axles, a somewhat weaker 4th vortex could be added at the bottom.
