The IFS equations are as follows

x_n+1 = a x_n + b y_n + e

y_n+1 = c x_n + d y_n + f

The parameter table:

                   set 1       set 2      set 3  
             a     0.387       0.441     -0.468
             b     0.430      -0.091      0.020
             c     0.430      -0.009     -0.113
