Visualisation of the velocity channel maps of the ¹²CO J = 3−2 emission of the circumstellar environment of L₂ Pup with the continuum subtracted. Each panel has a dimension of 1′′ by 1′′. The velocity channel is indicated in the top left corner of each panel. The black contour levels are drawn every 7 times the rms noise value outside the line. The white dot represents the location of the centre of mass.
