Sector block

A 'sector block is a region of space comprised of a number of individual sector regions, usually around 100 in number. The boundaries of a sector block are determined, by Federation reckoning, along with radial axes originating in the center of the galaxy. Groups of sector blocks numbering 900 or more make up a larger measurement, the sector quad.

In the Alpha and Beta Quadrant locality surrounding the Federation, sector blocks tend to measure 100 light-years by 100 light-years in width, and 80 light-years in height, accounting for the curvature created by the distance from the galaxy's center, laid out in a 9 ly by 10 ly by 10 ly grid.
