Fig. 4


Velocity position diagrams of the H2CO(30,3−20,2), HDCO(41,4−31,3), D2CO(40,4−30,3), and C18O(3 − 2) lines along the declination axis at Δα = 0′′. The molecule is indicated in each panel. The C18O(3 − 2) data are from Liseau et al. (2010). The vertical scale in each panel indicates the declination offset and the horizontal scale is the vLSR velocity. The intensity scale in all four panels is Tmb.
