I'm pretty certain that the following systems do belong to their respective races:
Terran Systems: Sol, Delta Serpentis, Beta Aquilae, Capella, Polaris, Regulus, Sirius, Epsilon Pegasi, Ross 128.
Vasudan Systems: Vasuda, Deneb, Aldebaraan, Alpha Centauri, Altair.
I'm not so certain on which side Vega, Antares, Beta Cygni, Betelgeuse, Ribos and Ikeya were originally on, because Vega could've been originally Terran before it was taken over by Vasudans and Antares and the other 4 systems only accessible through it could've been Vasudan territory before the Terrans began to invade them.
