Fig. 6
Median parallax of the sources within the TGAS S = 3 levels over bins of 1 × 1 degrees. Along 200°<l< 212° a gradient in the parallaxes is visible, suggesting that the density enhancements visible in Fig. 4 have different distances; the density enhancement associated with 25 Ori is closer than that associated with NGC 1980. The λ Ori group is visible at l ~ 195°.
