Profiles of a selection of DIBs with various strengths and widths are displayed with respect to the heliocentric radial velocity. Weaker (or nearly equal) and stronger DIBs in Tc 1 (in black) relative to HR 6334 (in red) are displayed in the left and right panels, respectively. The profiles are shifted vertically for clarity. The CH, CH⁺, and Ca I profiles at the bottom show the two interstellar components at −6.8 and +25 km s^-1 (marked with blue vertical dotted lines) seen in both sources. The sharper DIBs in both Tc 1 and HR 6334 also show these two components. The DIBs displayed in the left panel are consistent with the lower reddening of E(BV) = 0.23 for Tc 1 as compared to E(B − V) = 0.42 for HR 6334. The right panel, however, shows that the carrier(s) of these DIBs are enhanced (for the given E(B − V)) in the sight line to Tc 1.
