This appendix specifies which bursts are included in each one of the five samples used in this study. To facilitate its reading each column was named in reference to the discriminating parameter for each subsample. That is:
Sample 1: all 111 FREDs detected by Swift beforeMarch 2011.
Sample 2: 77 FREDs without any measured redshift different from zero
Sample 3: 71 FREDs without any claimed high redshift criteria
Sample 4: 59 FREDs without any type of indirect redshift indication
Sample 5: 49 FREDs without any redshift indications or multiple peaks
With the exception of the first column and where noted otherwise, each number refers to the GCN circular.
