COSMOS SC4K Catalog Definitions

Overview

The full Slicing COSMOS with 4K Lyman-alpha emitters (SC4K) catalogue of candidate LAEs is provided as released in Sobral et al. (2018). The SC4K catalogue contains the samples obtained with 12 COSMOS medium-bands, together with 4 narrow-band samples from Santos et al. (2016), Sobral et al. (2017b), Matthee et al. (2017b) and Perez et al.

For more information, see the README.
