HCO⁺(4–3) integrated intensity map obtained with ALMA in the CND of NGC 1068 using the MSR data set as defined in Table 1. The map is shown in color scale spanning the range [3σ, 40σ] with contour levels −5σ (dashed contour), 5σ, 7σ, 12σ, 20σ, and 30σ where 1σ = 33 mJy km s⁻¹ beam⁻¹. Symbols and markers as in Fig. 3. The (red) filled ellipse at the bottom left corner represents the beam size in HCO⁺(4–3) ( at PA = 78°).
