Longitudinal position–velocity (PV) diagrams along the crest of VCF 32 for the ¹³CO(2–1) and C¹⁸O(2–1) emission (left and right, respectively). The PV maps are in units of K(T_MB). Each PV diagram is perpendicular to the crest and averaged over 4 pixels (2×beams). The slices from 1 to 5 correspond to positions along the crest from east to west. The central positions of the slices are indicated on Fig. B.3. The white contours indicate the ¹³CO(2–1) intensity of 1 K and 2 K and are the same for the two panels of the same slice. The zero offset position (on the x-axes) corresponds to the Galactic south side of the filament systems. At the distance of this cloud 10’ corresponds to 3.8 pc. The position of the filaments is between 9’ and 10’.
