Opacity distribution in vertical planes containing the Sun, equally spaced by 15°. The north pole direction b =  + 90° is at the top and longitudes of intersections with the Galactic plane are indicated. Some iso-differential opacity contours have been superimposed to help visualize the low- and high-opacity regions. OB associations from De Zeeuw (1999), as well as CO and HI clouds listed by Perrot & Grenier (2003) have been displayed when they are within 25 pc of this vertical plane. We also add the molecular cloud locations derived by Knude (2010). The tenuous cloud close to the north pole direction.
