A demonstration of our ring-based analysis of the cloud. The spacing of the rings are 2.7 pc, which is comparable to the beam size (which is 2.2 pc). The blue solid lines stand for the region within which the emission is analysed. The cut was made at , This corresponds to 3.5 times the rms noise level. The red contours denote the boundaries of the rings that we use to divide and analyse the kinematic structure of the Spiral Cloud.
