Integrated intensity (moment 0) maps of molecular gas tracers, shown with a pixel size of 10″. (a): CO (1 − 0) map with contours at levels of 15–35σ in steps of 5σ (σ = 4.34 K km s⁻¹). (b): CO (3 − 2) map with contours from 13 to 57σ in steps of 11σ (σ = 2.39 K km s⁻¹). (c): HCN (4 − 3) map with contours from 3 to 12σ in steps of 3σ (σ = 0.38 K km s⁻¹). (d): HCO⁺ (4 − 3) map with contours from 3 to 6σ in steps of 1σ (σ = 0.41 K km s⁻¹). The white cross marks the location of the AGN in NGC 1068. Pixels with S/Ns below 3 are masked. The beam size and scale bar are shown in the lower-left corner of each panel.
