All Tables

Table 1: Observed stars. Columns headings are: Star - object name, V - V magnitude, E(B-V) - reddening, Sp - spectral and luminosity class.
Table 2: The equivalent width of DIBs (mÅ) measured in spectra of program stars.
Table 3: The column densities ( $\times10^{13}~\rm cm^{-2}$ ) of the C $_2\ X^1\Sigma ^+_g\ (\nu \hbox {$^{\prime \prime }$ }=0)$ rotational levels ( $J\hbox {$^{\prime \prime }$ }$ ). The values written in boldface are derived from the (2-0) band of the C $_2\ A^1\Pi _u\ -\ X^1\Sigma ^+_g$ Phillips System. The values written in plain text were calculated from the Boltzmann distribution.
