1.3 mm (231 GHz, left panel) and 3.3 mm (94 GHz, right panel) PdBI dust continuum emission maps of L1448-2A, corrected for primary beam attenuation. The ellipses in the bottom left corner show the respective synthesized beam sizes. The contours are levels of −3σ (dashed), 5σ, and 10σ, then from 20σ in steps of 20σ (rms noise computed in the map before primary beam correction, reported in Table 2). The blue and red arrows show the direction of the protostellar jet(s) either as found in our CALYPSO dataset or from the literature (see Table 1).
