SVS13-A region as observed in dust continuum emission using IRAM NOEMA. Left panel: image at 3 mm (see Sect. 2). Angular offset are with respect to the phase center (see Sect. 3). First contour and steps are 5σ (1σ = 100μJy) and 50σ, respectively. The filled ellipse shows the synthesized beam (HPBW): 1.′′6 × 1.′′1 (PA = 41°). The SVS13-B, SVS13-C, and VLA3 protostars are also labelled. White dashed circle indicate the primary beam: ~55′′. Right panel:zoom-in of the inner SVS13-A region as observed in dust continuum at 1.3 mm. First contour and steps are 5σ (1σ = 1 mJy) and 30σ, respectively. Symbols are as in the left panel. The synthesized beam (HPBW) is 0.′′ 6 × 0.′′6 (PA = –46°), while the primary beam is 24′′.
