\caption{\label{TabTriangles1}Physical and chemical characteristics of two TDR-models defined by
their parameters~$n_{\rm H}$, $A_{\rm V}$ and $a$. $f_{\rm M}(X)$, $f_{\rm VA}(X)$ and $f_{\rm VR}(X)$ are the contributions of the ambient medium, the active and the relaxation phases respectively, to the column density~$N(X)$ of the species~$X$. All models are computed for $N_{\rm
H} = 1.8$~$\times$ $10^{21}~\rm{cm}^{-2}$. The relative abundances are given in the last columns. Numbers in parenthesis are powers of~10.}

$^a$ For the reason given in Sect. \ref{contributions} $f_{\rm VA}({\rm H})= f_{\rm VR}({\rm H}) = f_{\rm VA}({\rm H_2}) = f_{\rm VR}({\rm H_2}) = 0$, because the densities of H and H$_2$ are not modified in the vortex.
