Top: equivalent width maps with DIBs 5780, 5797; center: DIB 6283 and K I ; bottom: maps of doublet line ratios for Na I D and K I , indicating optical depth. For each map, the ≈10 000 selected spectra were combined into 31 Voronoi bins. The color bar shows the equivalent width range as well as the average value for the species. The uncertainty is in the order of 8 mÅ.
