The "Dumbbell Sector Systems List" sheet hopefully has all of the systems in the sector listed but it's quite likely that we've missed some or alot. We've already added several missing systems (multiple times). Manually adding all of them was quite a challenge.

If you find systems like HD 190150 or non-dumbbell systems in the region you can add them too, those are easy to miss.
The "Dumbbell Sector Planets of Interest" sheet simply lists all of the systems with high value planets, possibly for future terraforming and colonisation.
