Distribution of the velocity gradients. The blue dots correspond to the values calculated from the ¹³CO data and thered dots to the values calculated using the C¹⁸O data. Theblue and red dotted lines indicates the average values of the gradients. The black triangles (¹³CO) and green squares (C¹⁸O) correspond to the different gradients calculated along the filaments F1, F2, F5, and F7. The Zones (ZI, ZII, and ZIII) labeled in those filaments correspond to those indicated in their respective velocity diagrams (e.g., Fig. 10).
