Javelin bootstrap results from HE 0413 with 1500 realisations for all the seven curves (from left to right) along with total MgII and FeII (last two plots of the lower panel). The peak and results from this are listed in Table 3. We also use the alias mitigation using down-weighting by the overlapping pairs. The black histogram represents the original delay distribution and the red one is after alias mitigation.
