Integrated HI emission flux measurements for the three regions defined in Fig. 5 together with corresponding HI mass estimates from Eq. (1).
| Region | Flux [Jy km s-1] | MHI [M⊙] |
|
|
||
| North (NGC 4418) | 1.47 | 4.0 × 108 |
| Middle (VV 655) | 4.05 | 11.0 × 108 |
| South | 0.83 | 2.3 × 108 |
|

| Sum | 6.35 | 17.3 × 108 |
Notes. Note that these values were obtained after removing the absorption towards NGC 4418, as described in Sect. 3.4.
