Is this intended? Am i interpreting the "binary" wrong? Is it non-binary when stars are closely clumped together, and not just in the same system screen?
If you're in the system map, and there are two stars, then it's a binary. If you're in the system map, and there's only one star (or three), it is not a binary. Where the stars are located on the hyperspace map doesn't matter.
Generally binary stars on the hyperspace map are closer together than isolated stars, but not always. Given the way mapping from a system to hyperspace works, it's quite possible for a crowded system with two stars and many planets to have the stars be surprisingly far apart in hyperspace. Conversely, two empty systems with a single jump point each can be very close together. I've certainly been uncertain looking at the map and trying to figure out which ones actually share a system, and once in a while gotten it wrong. Especially if the stars all have unique names.
Without seeing the system maps, I could not guarantee with 100% certainty which of those stars in the constellation are in binary. Probably 95% certainty, but I've seen exceptions.
