Heliocentric Galactic Cartesian coordinates of the ρ Oph sources. The known sources from the literature are marked with blue dots, the new sources with red dots, and impostor sources (Sect. 2.2) with black crosses (see legend). No quality or stability criteria were applied to the displayed sources. The black arrows in each panel indicate the line-of-sight from the Sun, pointing toward the star ρ Oph and plotted from d = 100–110 pc, which results in different arrow lengths due to projection effects. An interactive 3D version is available online.
