1. Figure 8 Global H i emission profile of NGC 6907 and 6908
Figure 8 Global H i emission profile of NGC 6907 and The bottom dotted lines limit the noise level while the top dotted line indicates the maximum emission h. Inside the distribution, two horizontal dashed lines are used to mark the H i line-widths estimated at 20 per cent (w₂₀) and at 50 per cent (w₅₀) of the peak intensities; v is the central weighted mean velocity distribution.
