ALMA CO(2−1) integrated intensity map of NGC 5643 produced from the natural-weight data cube. The map is shown on a linear color scale. Black contours corresponds to the CO(2−1) emission map. They are shown on a logarithmic scale with the first contour at 3σ and the last contour at 2.2 × 10⁻¹⁷ erg s⁻¹ cm² beam⁻¹. Brown contours correspond to the [O III]λ5007 Å emission map (see Sect. 4). The dashed black line indicates the kinematic major axis. The solid green line corresponds to the direction of the large-scale stellar bar (Mulchaey et al. 1997). Red and black boxes correspond to regions where streaming motions (local inflow) are expected and are not expected, respectively. For instance, region 5ne consists of 2 × 5 black boxes (1.2″ × 1.2″ square apertures), and the eastern 5 full slice corresponds to 5ne+5se.
