Three-dimensional distribution of dust in vertical planes containing the Sun and crossing the Taurus, Orion, and Cepheus clouds. The north Galactic pole is toward the top in each figure. The cloud distribution is based on Lallement et al. (2019). For each cloud group, two vertical planes are selected in such a way that the number of target sightlines falling very close to at least one of the two planes is maximized. The Galactic longitudes corresponding to each plane are indicated in the bottom-right corner of each figure. The dashed black line encloses the densest structures (see text).
