The IFS equations are as follows

xn+1 = a xn + b yn + e

yn+1 = c xn + d yn + 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
             d    -0.387      -0.322      0.015
             e     0.2560      0.4219     0.4
