Notes.

(†)

The bursts numbers are those from the burst catalog partly published in Galloway et al. (2008).

(‡)

Uncertainties are only provided for α since only power-law fits are acceptable.

(§)

Sometimes two values for are provided. The fitted values for α apply to the low value of (see text).
