On families of periodic solutions to the restricted three-body problem

We consider the plane circular restricted three-body problem. It is described by the autonomous Hamiltonian system with two degrees of freedom and one small parameter $\mu\in[0,1/2]$ which is the mass ratio of the two massive bodies. Periodic solutions to this problem form two-parameter families. We propose methods of computation of symmetric periodic solutions for all values of parameter $\mu$. Each solution has period and two traces, namely, the plane and the vertical one. Two characteristics of a family, i.e. its intersection with the symmetry plane, are plotted in the three coordinate systems: one global and two local ones related to the two massive bodies. We also describe generating families, i.e. the limits of families as $\mu\to0$, which are known explicitly.
