Figure 10:

Position-velocity diagrams for the three slit positions observed of IRAS 08208+2816 using the [O III] $\lambda$ 5007 profile. N is up in all diagrams. We have included the position of the regions (see Fig. 9 in Paper I for their identification), emphasizing those analyzed by spectroscopy. Notice that the lacking of data at the southern edge of the southern tail in the diagrams with PA 345 $^{\circ }$ and 355 $^{\circ }$ is because of the contamination by a bright star.
