Potential new detection of weak C₂-DIBs at 4737.5, 5547.4, and 5769.8 Å (they appear toward sigthlines where the other C₂ -DIBs are well-detected). The red dashed line shows the DIB location. Top graphs (black) in all three panels: extracted average normalized profile of C2-DIBs created from stacking three single-cloud targets: HD 23180, HD 203532, and HD 147889, shown below. Middle in all three panels: overlaid C₂ -DIB profiles at the same vertical scale for all stars. Bottom in all three panels: same C₂ -DIB vertically displaced and depth-equalized profiles. The red dashed line shows the DIB location. The wavelengths are in the interstellar rest frame. See Fig. 1 for color coding.
