Radial velocity profile derived from the MWISP 12CO images. The left panel shows the radial velocity profile derived from the Vobs − VLOS image. Red points show the data extracted from the image, and the blue curve is the best fit using the piecewise function. The right panel shows the 3D distribution of the recovered velocity plane using the profile in the left panel.
