Velocity-integrated intensity maps of the HCN(3-2) (upper row) and H¹³CN(3-2) lines (lower row), covering three velocity intervals. Left: Blue line wing [v_lsr,* − 10,v_lsr,* − 2] km s⁻¹, Middle: line center [v_lsr,* − 2,v_lsr,* + 2] km s⁻¹, Right: Red line wing [v_lsr,* + 2,v_lsr,* + 10] km s⁻¹. North is up and east is to the left. We note the different color scales. Contours are plotted every 10σ for HCN andevery 3σ for H¹³CN, where (from left to right) 1σ = 5.7, 7.2, 7.2 mJy/beam km s⁻¹ for HCN(3-2) and 1σ = 5.2, 5.0, 5.6 mJy/beam km s⁻¹ for H¹³CN(3-2). The black ellipse in the lower left corner indicates the synthesized beam. We note that the HCN maps were produced using robust weighting, whereas for the H¹³CN maps, we applied natural weighting.
