Argus sector

The Argus sector was a spatial region in the Alpha Quadrant. This sector was named after the Argus system.

In 2370, the USS Enterprise-D was originally assigned to this sector, but Admiral Chekote allowed the Enterprise to postpone its mission there and search for a band of mercenaries which had apparently murdered Captain Picard. (TNG: "Gambit, Part I")

This sector was only mentioned in dialogue.
StarTrek.com stated that this sector was named for a star with that name. [1](X)
The Star Trek Encyclopedia, 4th ed., vol. 1, p. 44 located the Argus sector in Federation space.
