NStED is dedicated to collecting and serving important public data sets involved in the search for and characterization of exoplanets and their host stars.
The NStED collects and serves public data to support the search for and characterization of extra-solar planets (exoplanets) and their host stars.
As of June 2007, the database catalogued 140,230 stars,[1] but by December 2011, SDtED was no longer in operation.
Data are searchable either for an individual star or by stellar and planetary properties.
NStED offers direct access to frequently accessed tables: NStED also serves photometric time-series data from surveys that aim to discover transiting exoplanets such as Kepler and the CoRoT.
