Cut in a 3D opacity cube derived by inversion of color excess data (Vergely et al. 2010), in a vertical plane containing the Sun and the two stars HD 142805 and 142315. Distances are in parsecs. The Sun is at (0, 0) coordinates. The North Galactic Pole corresponds to the Y axis and the X axis is in the Plane toward the longitude 350 degrees. Violet represents the densest clouds, while red corresponds to the lowest density. A black line joining the Sun and the star allows one to appreciate the ISM distribution along the line-of-sight. Most of the intervening interstellar matter (violet) corresponds to dense clouds and there are no bright hot stars close to the LOS. This may be linked to their normal 5780 Å DIB strength. The black circles show the UV stars from the Hipparcos catalog and the circle diameter scales with their ionizing power.
