Multi-resolution zeroth-moment maps of NGC 1566 (left panel) and NGC 5068 (right panel) based on the full-depth data. For each resolution, contours of 2ⁿ times the S/N = 3 value are shown (as listed in the legend). The resolutions shown are r05_t00 (red), r10_t00 (green), r15_t00 (blue), r05_t60 (purple), r10_t90 (olive). For each resolution two contours are shown, i.e., n = 0, 1, except for the highest resolution r05_t00 (red contour), where n = 0, 1, 2, … The r05_t00 moment map is shown in the background as a false color image, with the column density levels indicated by the color bar on the right. The beam sizes (colored according to the respective resolution) are shown in the bottom-right corner.
