Fig. 4

Galactic plane cut in the 3D opacity distribution resulting from the four successive inversions: panel a: A distribution: color excess data alone and Hipparcos or photometric distances. Panel b: B distribution: same as A except for the replacement of 80% of the initial distances with Gaia-DR1 (TGAS) values. For the 20% of stars without Gaia distance we kept the previous value. Panel c: C distribution: same as B except for the addition of DIB-based color excess estimates for stars with a Gaia-DR1 parallax. Panel d: D distribution: same as C except for the use of a Pan-STARRS based prior distribution instead of a homogeneous distribution. Color scale, direction of Galactic center, and Sun position are the same as in Fig. 3.
