Ah. Those are nice finds.
I spent about 30 minutes today, I noticed that terras around Red dwarf stars often have Co2 first, then N2 and O2. Seems to be a common theme.
I found this planet, which is the best I have managed to find so far. I think this planet would be a little warm for humanity, and the tidal locking would also be an issue. The air pressure is low. We may have to wear pressure suits or something like that on this planet, but after a few generations, perhaps a millenia humanity would probably adapt. It also has a rather busy sky and planetary system.
It would be like at being extreme extreme high altitude I think in terms of the oxygen levels.
EDIT: After searching around in the Triangulum Galaxy I found some more finds. Some of them aren't as promising though.
This one here is on the cold side, and the thin side.
This one is similary sized to earth, but it is boiling hot, literally.
This planet is quite cold, and its atmosphere is quite thin. No So2 though.
The last one here is on the hot and thin side.
And after more searching. It finally payed off. Found the crown jewel of all my finds so far.
