Thanks, mate - didn't think to look it up myself facepalm
Anyway, having two systems allows a few quick observations while comparing 52 Herculis <VS> Ooch Chrea:
The HGG have 97.10 HE% <VS> merely 0.13 HE%
The star type is A <VS> G
The GG have the same HE% (as usual) <VS> different HE% (0.13 HE% for the HGG and 25.58 HE% for the Class I GG) - which I think is notable
The HGG are mostly 2-3k EM (with one at 5k and a moon at 280) <VS> merely 11.9 EM
The differences are probably mostly due to manual authoring <VS> (seemingly) procedural generation. Might be worth looking into a little further, though probably still futile with only two samples and one of them being PG...
PS/Edit: Is anyone close to Ooch Chrea US-U d2-21 and able/willing to check/scan the other systems within that boxel? i.e. Ooch Chrea US-U d2-*
Thanks, Orvidius. A new addition to the "find one of these lists". That Galactic Center void is screaming for some OCD Rocket Jockey to break the mold. Although like many of you I suspect some cruel sadistic coder at FD did it just to drive us nuts.
