Halo scale length plotted as a function of total Lyα luminosities (upper panel) and total rest-frame Lyα EW (lower panel). Only the 121 LAEs with the EWs from the H17 sample are included for the lower panel. Our results are shown by the purple dots while W16 results correspond to the black dots. Arrows show upper limits. Values from studies using stacking methods are indicated by coloured symbols: X17 (red circles for their stacked images of LAEs from a protocluster field (PCF), and blue squares around a Lyα blob (LAB)), Momose et al. (2016, orange), Momose et al. (2014, blue), Feldmeier et al. (2013, magenta), and Steidel et al. (2011, green). Spearman rank correlation coefficients ρ_s and corresponding p₀ values for our results and those of W16 (without upper and lower limits) are shown in each panel.
