Dependences P(k) (a–c), H(P) (d–f), \(\Theta (k)\) (g–i), and \(\theta (P)\) (j–l) for the families of antisymmetric solitons and those with broken antisymmetry, generated by the numerical solution of Eq. ( 7) with \(\sigma =-1\), three different values of \(\varepsilon\), which are indicated in the panels, and the \(\delta\)-function approximated by expression (9). Counterparts of these dependences in the system with \(\sigma =+1\) are displayed above in Figs. 8, 9, 7, and 4, respectively.
