    • We remark here that also all relativistic mean field approaches in the presently used approximation scheme are predicting a stiff-like symmetry term, proportional to the baryon density, coming from the ρ-meson field contribution, see Ref. [10]. Actually, a superstiff-like behavior is obtained when a coupling to the scalar charged meson δ is added, see Refs. [11-13]

    • We like to call the r-r1-correlation plot as Wilczynski-2 plot. Indeed this correlation, very important to rule-out a statistical fission scenario for fragments produced at mid-rapidity, nicely emerged during hot discussions with Janusz the LNS - INFN, Catania. As shown in the discussion this correlation represents also a chronometer of the fragment formation mechanism. In this sense it is the nice Fermi energy complement of the famous Wilczynski plot which gives the time-scales in deep inelastic collisions

    • The solid lines in Fig. 4 are not fully symmetric with respect to the α=0 dashed line. This is due to the fact that, for fixed baryon density, the total scalar density which gives the σ field contribution (first part of the Eq. (6)) is also slightly N/Z dependent

    • In our framework this is a characteristic relativistic effect that should be somewhat included in the corresponding non-relativistic models. The importance of this contribution was not realized so far in previous non-relativistic studies [281], where no isospin effects were included in the momentum-dependent part of the effective forces. In this case the differences in the used symmetry energy parametrizations at supra-normal densities were very pronounced and therefore they resulted in very large effects with respect to earlier neutron emission and particle production

    • Of course we can have other asymmetric NM instability regions, at higher baryon densities, with a different structure of the unstable modes [20]. Here some interactions are even predicting quite exciting isovector-like (species separation) unstable oscillations. Unfortunately all that appears out of the present experimental possibilities
