Galactic distribution of the DIBs λ5780 and λ6614 for the HQ samples. The upper panels show the number density of the background stars. The lower panels display the sky distribution of the strength of the DIBs with the color bar representing the median EW in each pixel. The black contours of the corresponding median E(B − V) at the level of 0.35 and 0.7 magnitude are overplotted in the median EW map. The resolution of the map is about 0.92° (N_side = 64) calculated by the HEALPix package.
