Similar to Fig. 5 but only showing the profile of the DIB. Wavelengths were shifted to the rest position of the Na I line, except for HD 147165 where K I was used. The profiles of the DIB towards HD 147165 and HD 144334 are compared by scaling the profiles to the same line depth. The numbers in brackets displayed within the legend correspond to the number of stacked spectra.
