The luminosity-redshift distribution of Swift LGRBs. The gray shaded region represents an approximate luminosity threshold for detection. The purple circles are the 39 LGRBs at 3.5 ≤ z < 4.5 used as our benchmark. The 36 bursts at z ≥ 4.5 are separated into different redshift bins (orange shaded bands) used to estimate the high-redshift SFRD.
