Appendix A: Atlas

The Appendix contains summary panels for all galaxies of our sample (Figs. A.1-A.11) and channel maps for the galaxies from the rotation curve sub-sample (Figs. A.12-A.17).

The summary panels consist of two rows with three panels each, and contain the following maps:

Top row: Left panel: zeroth moment map with grayscales. Unless mentioned otherwise, grayscales run from a column density of $n_{\rm HI}=1\times 10^{19}\ {\rm cm}^{-2}$ (white) to $n_{\rm HI}=2\times 10^{21}\ {\rm cm}^{-2}$ (black). The 3$\sigma$ level is indicated by the black contour. Middle panel: first moment map. The systemic velocity is indicated by the thick contour, the contours are spaced by 10 km s-1. The approaching side can be identified by the light grayscales and black contours, and the receding side by dark grayscales and white contours. Right panel: second moment map. Grayscales run from 2 to 40 km s-1. Unless mentioned otherwise, the contours levels are given at 5, 10, and 15 km s-1. For all moment maps, the beam size is indicated in the bottom right corner. Additionally, if a kinematic center has been independently derived, it is indicated in all moment maps by a cross.

Bottom row: Left panel: major axis position-velocity diagram. The position angle of the slice indicated in the top-left corner of the panel. Grayscales run from 2$\sigma$ to 30$\sigma$, and contour levels are given at $2\sigma + n \times 4\sigma$ (i.e., 2, 6, 10, 14, 18 ... $\sigma$). The dashed line indicates the systemic velocity. If a Vpv has been derived, the resulting velocities at either side of the rotation curve are indicated by arrows. Middle panel: minor axis position-velocity diagram. Grayscales and contours are identical to the major axis position-velocity diagram. Right panel: global H  I profile of the Hanning smoothed data cube.
