Fig. (12) (Color on line). Log of the exotic meson masses versus the log of the rank. The SPES3 data [8-10] are shown with solid red circles; the Dubna data  with empty purple crosses; the Lear data with p
at rest  empty blue squares, the Lear data with p
movement  by blue star, the Uppsala data  with solid green
triangles. The PDG masses  are also introduced, and are
represented by black stars.
