Previously (Paper I) large-scale splitting of the [N II] line was discovered over an area of IC 1318b. The motions of the ionized material have now been mapped over a much larger region of this nebula and also IC 1318 c. The splitting reaches a maximum value of 53 km!s over the faintest regions of IC 1318 b and occurs over an area ≳ 20 pc across.
However, few split [N II] lines were found over IC 13 18c, but the motions of this whole ionized and neutral complex have been shown to be closely related. Wind-driven flows along neutral and ionized shells are proposed to explain the observations. Similar measurements have also been made on either side of the dark lane separating NGC 7000 from IC 5070.
