Comparison of two measures of the Lyα strength, and EW(Lyα), of LCEs with that of GPs, LBAs, and LARS: strong LCEs, shown by large black stars, are more extreme than the comparison samples. The open symbols show the median of the distributions for each sample. The red star shows the location of the high-redshift strong LyC leaker Ion2. The dashed lines delimit the upper right panel containing all strong LyC leakers.
