A starter which produces necessary data to generate a Homoclinic-to-Saddle-Node curve from a Non-Central Homoclinic-to-Saddle-Node orbit (NCH) has the following parameters that can be modified via the starter window.

 

Initial point

 

p

a list of parameter names and their values.

Homoclinic parameters
 
T contains the value of half the stored time interval of the orbit.
eps0 contains the value the distance of the first orbit point to the equilibrium.
eps1 contains the value the distance of the last orbit point to the equilibrium.
