Eiso distribution for long (blue hatched histogram) and short (red hatched histogram). For long bursts the distribution has mean and median values of 1.4 × 1053 erg and 1.2 × 1053 erg, respectively. A log-normal fit to the long bursts (dashed line) peaks at 1.2 × 1053 erg with a FWHM = 1.9 in log-space. Short bursts have a mean and median value of 4 × 1051 erg and 2.9 × 1051 erg, respectively. A log-normal fit to the combined sample (dash-dotted line) peaks at 9.8 × 1052 erg with a FWHM = 2.2 in log-space.
