NStED: Exo-Planet Transit Survey KELT Search

NStED provides access to high precision time series photometry from stars observed by various transit survey programs. The data have been donated by astronomers who have sought to search for extra-solar planets via photometric transits of the planets around the host stars. The photometric surveys are of specific regions of the sky (e.g., field stars, open clusters etc). Each survey in the archive has different characteristics (e.g., field location, field size, filters in which time-series photometry was performed, magnitude ranges).
