Rest-frame M₁₄₅₀ binned luminosity functions of our Boötes RSQ samples (colored circles) for four non-overlapping redshift intervals between 1.4 <  z <  5.0. The lines show the corresponding best-fit models in each redshift bin. The best-fitting parameters for each fit are presented in Table 6. For comparison, we show the QLFs from previous works (Cirasuolo et al. 2005; Siana et al. 2008; McGreer et al. 2009, 2018; Glikman et al. 2011; Masters et al. 2012; Ross et al. 2013; Giallongo et al. 2015; Tuccillo et al. 2015; Akiyama et al. 2018) measured over similar redshift intervals. The single-power law fits by McGreer et al. (2009) and Tuccillo et al. (2015) are plotted in the range −29 ≤ M₁₄₅₀ ≤ −26, which is the original range where they were measured.
