It turns out to be useful to look at a sequence of values of a, a0 , a1 .... given by

am = ac - C delta -m

where ac depends on the map function , but delta = 4.6692016091... for all maps. The value of m can be used to step through values of a yielding 2m orbits (the symbol I in the list box for m corresponds to infinity i.e. a=ac). The value of C can be chosen to give particular "types" of orbit.

The list boxes respectively:

Values can also be typed directly into the text boxes (remember to Enter or Reset).
