Our galaxy is divided into four quadrants, defined by one meridian passing through the galactic core and the Sol system and a second one perpendicular to the first, that also passes through the galactic core.
A sector is a much smaller volume of space measuring 20 cubic lightyears. Sectors typically contain several stars and are consecutively numbered; some also have a label, normally, but not always, named after an important star system in that sector.
