Fig. 11
Averaged expansion velocity from Torun models compared with pyCloudy. The abscissa shows the Torun models mass-averaged velocities, while at ordinate the pyCloudy Hβ-averaged values are shown as filled symbols, and the pyCloudy mass-averaged as open symbols. The (red) circles show the bipolar nebulae and the (blue) squares the post-bipolars. Data from Table A.1.
