\caption{Observational and measurement data. Given are: star name
(observed at t -- Terskol (Russia), f -- FEROS, H -- HARPS La Silla
(Chile),  b~-- Bohyunsan (S.Korea)), spectral and
luminosity class, reddening, {\it EW}s (m\AA) of CH$^{+}$ at 3597~\AA\
and 4232~\AA, column densities of CH$^{+}$ (obtained on the basis 
of $f$-values equal to 0.00331 and 0.00545 respectively), and column
density of H$_{2}$ and H$_{\rm tot}$. Data for hydrogen were taken 
from Savage et~al. (\cite{Sava77}), in case of:
$^{R}$ -- Rachford et~al. (\cite{Rach02}),
$^{C}$ -- Cecchi-Pestellini \cite{Cecc07}, $^{P}$ -- Pan et~al. (\cite{Pan04}),
$^{B}$ -- Burgh et~al. (\cite{bu07}).
With $\bf{^{x}}$ -- we designate lines of sight in case of which
$N$(CH$^{+}$) was obtained on the basis of unsaturated 
3957~\AA\ line.}\label{tab1}
