Data Sets in NED
Data Sets in NED
(Latest revision: 12 Nov 2021)
Very large survey catalogs typically require specialized processing to transform
selected fields into the form required for cross-matching and integration into
NED's generalized database, which is designed to join data across missions and
surveys. They also contain many metadata fields that flag special conditions and
caveats for the primary data entries. These pages describe how some of these
issues were handled while integrating specific data sets into NED.
