PILS ALMA continuum map of the IRAS 16293−2422 system at 850 μm. The background image shows the continuum emission, the contours indicate the H₂C¹⁷O 5_2,3 –4_2,2 line (E_u = 98.5 K) integrated emission, the star is the position of the continuum peak, and the plus sign the position of the extracted spectrum (one beam, i.e., 0.′′5, away from the continuum). The continuum image is cut off at 15 mJy (3σ) and the line contours start at 25 mJy km s⁻¹ (5σ) in steps of 120 mJy km s⁻¹.
