Database Contents

Tabular summaries of NED's current holdings are presented here. Graphic summaries are presented here. After the ingestion of the AllWISE Source Catalog, NED now has over 1.1 billion distinct objects, and about 14 billion photometric data points.

AllWISE Source Catalog

  • All 747,634,026 sources from the AllWISE Source Catalog (Cutri, R. M. et al. 2013wise.rept....1C ) were integrated into NED. Out of them, 307,940,233 matched with existing NED objects, 439,693,793 became new distinct objects.

References and Object Pointers

1,048,072 new object links (pointers) and 2,032 new references including:
