Abstract

It is shown that the contribution of faint gamma-ray bursts (GRBs) to the total all-sky GRB energy flux is small. The all-sky flux of GRBs appears to be 5.3 × 10^-3ergcm^-2yr^-1, with little additional component hidden within weak or otherwise undetectable GRBs. This significantly constrains physical models of GRBs and dirty fireballs, suggesting a rather sharp dichotomy between them should the latter exist.
