The NED Local Volume Sample (NED-LVS) is a subset of NED that contains over 2 million objects with distances out to 1000 Mpc. The distances selected for NED-LVS are based on both redshifts (~99%) and redshift-independent distances integrated from the literature and large surveys. The data in NED are updated regularly, and new versions of NED-LVS are extracted periodically. Consequently, NED-LVS will continue to provide an increasingly complete sample of galaxies for a multitude of astrophysical research areas (star formation, galaxy evolution, large scale structure, galaxy environments, and searches for the electromagnetic counterparts to gravitational wave events) for years to come.

NED-LVS is utilized by the NED gravitational wave follow up (NED-GWF) service, which provides downloadable galaxy lists and visualizations for candidate host galaxies. For each GW alert issued by the International Gravitational Wave Network (IGWN), these products are automatically generated and made available within minutes to expedite efficient electromagnetic follow-up observations. The galaxy lists produced by NED-GWF also provide several pre-computed prioritization metrics (i.e., stellar mass, star formation rate, and specific star formation rate, etc.), which are available by downloading the entire galaxy list inside an event's probability volume.

The June 2025 version of NED-LVS includes new objects ingested by NED from the literature and the removal of newly identified non-galaxy contaminants. This revision contains a total of 2.10M objects, an increase of 33K (1.6%) over the previous version. Each release of NED-LVS is accompanied by an additional round of vetting for both newly ingested objects and subsets of the previous version to ensure a robust and highly complete census of the local Universe. Improvements for this version include 2.1K updated redshifts and 5removal of 5.7K non-galaxy contaminants (foreground Galactic stars, parts of galaxies, and duplicate objects with "unmatched data"). For further details and caveats, see the Latest Update (June 2025) section of the NED-LVS webpage.
