Local values of the ratio between the DIB carrier volume density as measured by the EW local spatial gradient (in units of Å pc−1 ) and the extinction volume density (in units of mag pc−1 ). The two DIB-to-dust ratio maps are for the same planes as in Figs. 3 and 4. Iso-contours of extinction density for two low values (10−5 (black) and 5 10−4 (violet) mag pc−1 ) are superimposed. -- astro-ph.GA

The carbonaceous macromolecules imprinting in astronomical spectra the numerous absorptions called Diffuse Interstellar Bands (DIBs) are omnipresent in the Galaxy and beyond and represent a considerable reservoir of organic matter.
