The equivalent widths of the 6196, 6379, and 6613 Å DIBs in lines-of-sight previously measured and included here are compared with the measurements obtained in this work. Literature values are taken from Herbig (1993); Seab & Snow (1995); Galazutdinov et al. (2002); Thorburn et al. (2003); Galazutdinov et al. (2004); Sollerman et al. (2005); Megier et al. (2001, 2005). Linear regressions with the corresponding correlation coefficients r are shown in each panel. Slopes and intercepts of these regressions are 1.06 and −0.8 mÅ, 1.13 and −3.1 mÅ, and 0.995 and −1.9 mÅ, for the 6196, 6379, and 6613 Å DIBs, respectively.
