Comparison of line flux measurements from different catalogues and methods. The Lyman α line flux from Hashimoto et al. (2017a) (top panel, on the x-axis) and the Lyman α line flux from Leclercq et al. (2017) (bottom panel) are compared to the measurements from LSDCat (y-axis, in the same fields using the same observational depths). The one-to-one relation is shown as the dashed line and the colour-coding and sizes of the dots correspond to the halo scale lengths rs_halo from Leclercq et al. (2017). The line flux measurement from Hashimoto et al. (2017a) is based on a curve-of-growth measurement from narrow-band images as described by Drake et al. (2017a,b), similar to Leclercq et al. (2017) who use an additional two-dimensional decomposition for the halo and continuum components of the LAEs.
