At the point $2$, when $J_{CSIs}=J_{CsFS},$ we arrive at the border between the *mode (1a)* and* mode (1b)*. It is seen that at this point there is maximum deviation of $J_{S}(\varphi )$ from the sinusoidal shape. Further increase of $d_{F}$ leads to $0$-$\pi $ transition, when parameter $\beta $ in ([SInFSotFI]{}) becomes small and $J_{S}(\varphi )$ practically restores its sinusoidal shape. Beyond the area of $0$ to $\pi $ transition, the critical current changes its sign and CPR starts to deform again. The deformation achieves its maximum at the point $7$ located at the other border between the *modes (1a)* and* (1b).* The displacement from the point 7 to the point 8 along the $J_{C}(d_{F})$ dependence leads to recovery of sinusoidal CPR.

Figure \[CPR\]c presents the transition from the $\pi $-state of *mode (1a)* to *mode (1b)* with $d_{F}$ increase. It is seen that the offset from the point $1$ to the points $2-5$ along $J_{C}(d_{F})$ results in transformation of the CPR similar to that shown in Fig.\[CPR\]b during displacement in the direction from the point $1$ to the points $2-6.$ The only difference is the starting negative sign of the critical current. However this behavior of CPR as well
