SMA/APEX integrated intensity line maps of all spectral lines in the SMA coverage except for ¹³CN N = 2–1, J = 5/2–3/2 (blend of several hyperfine transitions), which is barely detected in the interferometry data. The plotted ¹³CN line has the quantum numbers F₁ = 1–0, F = 0–1. No APEX short-spacing data were used for the ¹²CN N = 2–1, J = 5/2–3/2 (blend of several hyperfine transitions) line. All contour levels are at a 3σ level at the edge of the primary beam. Refer to Table 4 for the exact contour levels and the integration intervals. Refer to Fig. 1 for a guide to the symbols used for the compact objects.
