Notes. Columns 2–9: properties of the filters related to the Lyα line. From left to right: median redshift in the filter bandwidth, redshift associated to the filter pivot wavelength (see Tokunaga & Vacca 2005), redshift interval covered by the NB FWHM, effective DR1 area and volume (see Sect. 4.2), minimum detectable line flux and luminosity (both in linear and logarithmic units; see Sect. 2.2.1). Last four columns: redshift associated to strong QSO lines (e.g. Vanden Berk et al. 2001) which can act as contaminants in our selection.
