Equivalent widths of the λλ5780 and 5797 DIBs previously measured for sightlines included in this survey compared to values measured in this work. For several sightlines several literature values are available, illustrating the “intrinsic” scatter in equivalent widths due to measurement methods. 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); and Friedman et al. (2011). Linear regressions are shown in each panel. Correlation coefficients r are 0.99 and 0.96 for the 5780 and 5797 Å DIBs, respectively. Slopes and intercepts of these regressions are 1.02 and 11 mÅ for the 5780 Å DIB and 1.12 and −6 mÅ for the 5797 Å DIB, respectively.
