The LF and SFR density evolution for 0.4 < z < 2.2, as seen through a completely self-consistent analysis using HiZELS. The measurements are obtained at z = 0.4, 0.84, 1.47 and 2.23, correcting for 1 mag extinction at Hα. Columns present the redshift, break of the LF, L*, normalization (ϕ*) and faint-end slope (α) of the Hα LF. The two right-hand columns present the SFR density at each redshift based on integrating the LF down to ≈3 M yr−1 or 41.6 (in log  erg s−1) and for a full integration. SFR densities include a correction for AGN contamination of 10 per cent at z = 0.4 and 0.84 (see Garn et al. 2010) and 15 per cent at both z = 1.47 and 2.23. Errors on the faint-end slope α are the 1σ deviation from the best fit, when fitting the three parameters simultaneously. As α is very well constrained at all redshifts, and shown not to evolve significantly, L* and ϕ* are obtained by fixing α = −1.6, and the 1σ errors on L* and ϕ* are derived from such fits (with fixed α).

The LF and SFR density evolution for 0.4 < z < 2.2, as seen through a completely self-consistent analysis using HiZELS. The measurements are obtained at z = 0.4, 0.84, 1.47 and 2.23, correcting for 1 mag extinction at Hα. Columns present the redshift, break of the LF, L*, normalization (ϕ*) and faint-end slope (α) of the Hα LF. The two right-hand columns present the SFR density at each redshift based on integrating the LF down to ≈3 M yr−1 or 41.6 (in log  erg s−1) and for a full integration. SFR densities include a correction for AGN contamination of 10 per cent at z = 0.4 and 0.84 (see Garn et al. 2010) and 15 per cent at both z = 1.47 and 2.23. Errors on the faint-end slope α are the 1σ deviation from the best fit, when fitting the three parameters simultaneously. As α is very well constrained at all redshifts, and shown not to evolve significantly, L* and ϕ* are obtained by fixing α = −1.6, and the 1σ errors on L* and ϕ* are derived from such fits (with fixed α).
