Fig. 2
Continuum ALMA image centered at 231.17 GHz (1.3-mm) of the compact emission of the BN object. Only baselines with length B > 100 kλ were used to filter out the extended emission in the field. The BN object is detected as an unresolved source with flux density of 62 mJy. The rms noise around BN in this map is σ ~ 3 mJy.
