Gamma ray bursts remain a fertile area of investigation. What sets these blasts off?...concensus in the community according to some is Sne, collimated pencil-like bursts sent off in a couple of opposing directions(Shrinivas Kulkarni, MIT lecture @ Physics Colloquiem).
But, the way your algorithm triggers your burst detector plays quite a role in counting bursts and prefers hard ones over softer, dimmer ones, skewing the sampling some, with cosmological implications. SEE:http://arxiv.org/abs/0904.1464

Small number statistics plus selection effects equals less-than-precise cosmological conclusions multiplied by preconceptions.
