Map of the studied region between the Sun and Sco-Cen. The grey-shaded areas represent the dust map from Edenhofer et al. (2024) projected onto the XY-plane; the blue-shaded areas (brighter closer to the Galactic plane) show the Local Bubble map (−50 < Z < 50 pc; O’Neill et al. 2024) based on the same dust map. The orange stars show the positions of the objects from Redfield & Linsky (2008); brighter orange stars represent measurements with multiple velocity components. The larger blue stars indicate the positions (d = ϖ⁻¹) of our calcium-probing (mostly B-type) stars, with lines indicating distance uncertainties. The two arrows in the bottom-right corner show the directions towards the Galactic centre (up) and the Galactic rotation (left). The bar in the bottom-left corner (length of 100 pc) serves as a distance scale.
