Notes. Two velocity components with identical width of 0.11 Å are assumed to contribute to the total absorption profile. This corresponds to an intrinsic FWHM of 5.7 km s -1 (for resolution of 6.3 km s-1) and hence a b of 3.4 km s-1. The equivalent width and column density are given for the total line profile and the strongest velocity component, respectively. The average CN excitation temperature derived from the R0/R1 and R0/P1 ratios and the R0/R1 column density ratios are given for the strongest velocity component only.
