12CO (J = 1–0, top panel) and 13CO (J = 1–0, bottom panel) velocity channel maps after subtracting the components that are not associated with the B211/B213 filament. The intensity unit is K. The velocities in km s−1 are indicated in the top left corner of each panel. The velocity width of each channel map is 0.3 km s−1.
