Description The Next Generation Transit Survey (NGTS) is a ground-based exoplanet survey designed to detect Neptune and super-Earth sized planets around bright host stars using the transit method. This data release includes 24 fields covering a FoV of 2.8 x 2.8 sq.deg. This is the NGTS source catalogue and each source is cross-matched with various other catalogues
