Information on ℳ = 2 POs. Uppermost row (in red) shows the (x, y) view of families 2A, 2B, 2C, 2D, and 2E, as given in the upper right corner of the corresponding panel. The red filled circles show the location where the orbit intersects the x axis and the two red arrows show the directions of the corresponding velocity vectors. Middle row shows the same information but now for their symmetric orbits, i.e. from families 2A_s, 2B_s, 2C_s, 2D_s, and 2E_s, respectively (in green). Bottom row: we show the corresponding SoSs and the invariant points of the orbits from the first two rows. In all cases we use red for the first family and green for its symmetric counter part. See the text for more information. The blue filled circles indicate the position of the x1 orbit invariant point.
