NStED offers a powerful query and download engine to search for data on individual stars or to search for groups of stars by stellar and exoplanet parameters. All data in NStED are vetted by a team of astronomers and are directly linked to the original literature references.
NStED supports interactive visualization of catalog query results, images, spectra, and time series data, and on-the-fly calculation of stellar parameters. NStED maintains its own stellar cross-identification to minimize ambiguity in multiple star components.
NStED has a dedicated interface for transit survey data sets, including TrES observations of the Kepler field and KELT observations of the Praesepe field.
