Table 1: 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, EWs (mÅ) of CH+ at 3597 Å and 4232 Å, column densities of CH+ (obtained on the basis of f-values equal to 0.00331 and 0.00545 respectively), and column density of H2 and H $_{\rm tot}$. Data for hydrogen were taken from Savage et al. (1977), in case of: R - Rachford et al. (2002), C - Cecchi-Pestellini 2007, P - Pan et al. (2004), B - Burgh et al. (2007). With $\bf {^{x}}$ - we designate lines of sight in case of which N(CH+) was obtained on the basis of unsaturated 3957 Å line.
