Classical measure of regularity freg(E)

E = 0
FIRST -10 -5 -2 -1   +1 +2 +5 +10 LAST
freg(B=1.09,E) freg(B=1.09,E)
Figure 1: freg (B=1.09, E) The same as in Figure 1, but in different scale.
Calculated using the sections of regularity (see Figure 2).  
freg(B=1.09,E) Section of regularity (B=1.09,E=0)
The same as in Figure 1, but in different scale. Figure 2: Section of regularity
  Poincaré section y=0 calculated on a 100 x 100 grid. A trajectory is started at each point of the grid and the SALI method is used to distinguish regular (blue colour) from chaotic (red colour) trajectories.
