Top row: Moment 1 maps from PHANGS MeerKAT H I observations of NGC 1512, NGC 4535, and NGC 7496 built with the strict masking procedure described in Section 3. The maps are overplotted with isovelocity-lines (grey) in intervals of 30 km s−1. Middle row: Integrated intensity or Moment 0 maps from the MeerKAT H I observations built with the same masking procedure. The location of the companion galaxy NGC 1510 is indicated by the white circle. Bottom row: Integrated intensity or Moment 0 maps of the three galaxies built from CO observations taken from PHANGS-ALMA. The extent of the CO maps is indicated in comparison to the H I maps.
