Nearby Optical Galaxies: Selection of the Sample and Identification of Groups In this paper we describe the Nearby Optical Galaxy (NOG) sample, whichis a complete, distance-limited (cz=6000 km s-1) andmagnitude-limited (B: =14) sample of ~7000 optical galaxies.: Thesample covers 2/3 (8.27 sr) of the sky (|b|>20deg) andappears to have a good completeness in redshift (97%).
