Sector
From Warhammer 40k - Lexicanum
Each Segmentum is divided into Sectors. The size of a sector varies according to local demands and stellar density. A typical sector might encompass 7 million cubic light years, equivalent to a cube with sides almost 200 light years long. Sectors are in turn divided into Subsectors.
