(Top) 13CO integrated intensity map from the SEDIGISM survey in the velocity range −95 to −75 km s−1 showing a wave-like feature. (Bottom) 12CO integrated intensity map from the ThrUMMS survey in the same velocity range as the top panel, smoothed to an angular resolution of 5'. Images are stretched along the y-axis for a better visualization.
