Sector
A Sector is a astrophysical co-ordinate system applied to the galaxy. A sector is part of a Domain within the Imperium, and contrains sub-sectors.
Mapping unit in astrography equal to sixteen subsectors. Average density 500 to 650 worlds per sector. Sectors are named, and several synonyms are in common use, including march (or marches), region, reach (or reaches), quadrant, and matrix. The Spinward Marches, for example, is a sector.
As a rough means of comparing size, the sector counts of the large interstellar states and areas of settlement are: the Imperium: 19; the Aslan Hierate: 15; the Hive Federation:11; the Two Thousand Worlds: 9; the Vargr Extents: 9; the Zhodani Consulate: 8; the Solomani Confederation: 5.
Some sectors are known by other names (by non-imperial races), strangely enough they use the same co-ordinate system.
