Dust continuum emission at 3 mm (greyscale and contours) of the SVS13 multiple system observed with NOEMA using configurations C and D (setup 1; see Sect. 3). The first contours are at 3σ (210 μJy beam ⁻¹), and the steps are in 10σ. The synthesised beam (bottom left corner) is 2″.81 × 2″.23 (PA = 31^∘). The brightness peaks reveal the positions of the SVS13-A, VLA3, SVS13-B, and SVS13-C protostars (see text). The dashed circle delimitates the FoV of the 3 mm observations of 51″. The black triangles indicate the positions of the HH11 and HH10 Herbig-Haro objects (e.g. Bally et al. 1996).
