    The HST/ACS Coma Cluster Survey. II. Data Description and Source Catalogs
    The Coma cluster, Abell 1656, was the target of an HST-ACS Treasury program designed for deep imaging in the F475W and F814W passbands. Although our survey was...

    The Hα Galaxy Survey. II. Extinction and [NII] corrections to Hα fluxes
    We study the two main corrections generally applied to narrow-band Hα fluxes from galaxies in order to convert them to star formation rates, namely for [NII]...
