Kinematic maps and profile for the barely resolved ALMA mock data for the disk Opuntia at 30 (upper panels), 60 (medium panels) and 80 deg (bottom panels). Column 1: [C II] integrated spectrum (gray histogram) and best-fit model (solid green line), resulting from the sum of two components (red dashed and purple dotted lines). Column 2: moment-0 map with black contours showing the 3, 6 and 9 rms levels. Columns 3 and 4: moment-1 and moment-2 maps obtained following the methodology in Romano et al. (2021) (see Sect. 6.3 for details). The dashed lines in the moment-1 map show the directions of the major and minor axis along which the PV-diagrams are extracted. Columns 5 and 6: PV diagrams along the major (left) and minor (right) axis with contours at −2 rms (dashed gray lines) and 2, 4, 8 rms (solid black lines).
