Observational velocity–right ascension plot. Individual features are marked. The "southern filament" is a stream of gas extending to the south of the bridge, while the "southern arc" is gas to the southeast of the NGC 7714 disk (see Paper II and Fig. 19). Note that in both the NGC 7714 and NGC 7715 disks, the velocities tend to increase from east to west, as does the gas in the northwestern loop and the bridge. The velocity of the gas in the inner southwestern tail, however, decreases from east to west. As noted in the text, the long southwestern H I tail seen in low‐resolution H I maps (Paper I) has too low a surface brightness to be visible in this plot. It extends to R.A. 23^h33^m15^s (B1950.0) with a velocity of ~2850 km s⁻¹ (Paper I).
