Lyα EW vs. total stellar mass estimates. The horizontal black dashed line shows the 20 Å threshold a source has to exceed to be considered a LAE. For readability, the blue and red portions of the figure mark LAE and NLAE populations respectively. Red, blue, and green trends represent respectively the EW median values in Mass bin of 0.5 dex for GOODS-S, COSMOS, and UDS fields. They are associated with an error bar, accounting for the median absolute deviation.
