Mrk 1066. Panel a: CO(2-1) integrated intensity contours (as in Fig. 1) in blue overlaid on the V − H color map. Light colors indicate low extinction and dark colors high extinction. Panel b: ^3DBAROLO CO(2-1) observed velocity field. Panel c: ^3DBAROLO velocity model. Velocity contours in b and c panels are from 3540 to 3800 km s⁻¹ in steps of 20 km s⁻¹. Panel d: 1.3 mm continuum map with the contours at −6σ, −3σ (white dashed line), 3σ, 6σ, 9σ, 12σ, 15σ, and 18σ (white solid line), and σ = 41 μJy beam⁻¹. Panel e: residual velocity map. Contours are from −50 to 50 km s⁻¹ in steps of 10 km s⁻¹. Purple stars and ellipses mark the regions from which we extracted spectra (see Fig. 3). Panel f: ^3DBAROLO CO(2-1)-observed velocity dispersion map. Contours are in steps of 10 km s⁻¹, starting at 10 km s⁻¹. Ellipses in the bottom corners are the NOEMA-synthesized beam (see Table 3), and the red or black dashed (dotted) line is the major (minor) kinematic axis derived from the ^3DBAROLO fit (see Table 5). The white star marks the 1.3 mm continuum peak.
