Posterior distribution of the average time delays inferred from a simulated SGRB population while assuming different photon peak flux cuts. The dashed black line shows the ‘true’ average time delay value corresponding to the power-law DTD parameters from which the SGRB events have been sampled. The blue curve shows the result obtained with the same flux threshold cut as in our analysis, which ensures flux completeness of the sample. The yellow, green, and pink curves were obtained with lower threshold values, as reported in the legend.
