$^*$ Estimated based on SD-200~model. The elemental abundances assumed to deduce the model ionic abundances with respect to oxygen are given in Table~\ref{TabAbund}; $^{**}$~this line is partly arising in the pre-shock region. As follows from Table~\ref{TabLinRat},
the post-shock region contribution is $I/I$(5007~\AA$)\approx0.0025$.
