Argosian sector

From Memory Alpha, the free Star Trek reference.

The Argosian sector is a sector of space.

Deep Space 9's navigational computer held star charts to this region of space. However due to technical malfunctions, when Kira Nerys tried to access these, maps of the Glessene sector were retrieved instead. (DS9: "Babel")

Due to the naming of the sector, it seems probable that this would be the location of the Argosian homeworld.
