Hα redshift distribution above various flux thresholds (from 0.5 × 10^-16 erg cm^-2 s^-1 to 3 × 10^-16 erg cm^-2 s^-1, from top to bottom panels). Observed redshift distributions are indicated with open circles, while data obtained integrating LFs are shown with squares. HaLF predictions from Model 1, 2, 3 are shown as thick solid lines. The predictions from L12 mocks (green dashed and solid lines using intrinsic and extincted Hα fluxes, respectively) and GP14 mocks (dark and light grey for H< 27 and H< 24 mocks, respectively) are also shown.
