M₁₅₀₀ versus z_p for our sample and the literature. The M₁₅₀₀ and z_p of our parent sample from Rafelski et al. (2015) are shown by magenta filed circles (identical in the two panels). Upper panel: the M₁₅₀₀ cut () for our sample defined from the rest-frame UV HST bands is indicated by a black thick solid line. The parameter space studied here, X_LAE vs. M₁₅₀₀ at z ≈ 3–4 and X_LAE vs. z at z ≈ 3–6, is shown by a black solid polygon and a black dashed rectangle, respectively. Lower panel: the UV magnitude cut of F160W ≤ 27.5 mag at z ≈ 6 in De Barros et al. (2017) and UV magnitudes corresponding to ≈90% completeness at z ≈ 4, 5, and 6 in Arrabal Haro et al. (2018) are represented by a dark-grey arrow and dark-grey crosses, respectively. The apparent magnitude cut of F775W ≤ 26.5 mag in Caruana et al. (2018) is shown by a grey solid line. The parameter space for the faint galaxies studied in Stark et al. (2011) is indicated by a light-grey shaded region.
