Background

Before getting to the meat of the problem, it's important to have a good idea of how the procedurally generated parts of the E:D galaxy is laid out.

The galaxy is divided into sectors, each of which have a unique name; each sector is a cube, 1280x1280x1280Ly in size. Every system in the galaxy belongs to exactly one procedurally-generated sector, although due to the presence of hand-crafted content, a system may not bear the name of the PG sector it's actually part of.

For example, both Sol and Col 285 Sector FH-I b11-1 are actually in the Wregoe sector. The latter example is slightly confusing: despite having the same form as a fully procedurally generated system, the sector itself (Col 285) is hand-placed and "overrides" the Wregoe systems that would normally appear there.

These sectors do not align neatly to the coordinate space we know and love; the nearest sector "corner" boundary to Sol is at coordinates [-65, -25, 215]. The reason for this oddity is potentially explained by knowing that Frontier internally appear to use different coordinates which put Sol at [49985, 40985, 24105]. The boundary coordinates shown earlier match a coordinate system with such an origin (e.g. 49985-65 is a multiple of 1280).
