Correlative Analysis of GRBs detected by Swift, Konus and HETE

Swift has now detected a large enough sample of gamma‐ray bursts (GRBs) to allow correlation studies of burst parameters. Such studies of earlier data sets have yielded important results leading to further understanding of burst parameters and classifications. This work focusses on seventeen Swift bursts that have also been detected either by Konus‐Wind or HETE‐II, providing high energy spectra and fits to E_peak . Eight of these bursts have spectroscopic redshifts and for others we can estimate redshifts using the variability/luminosity relationship. We can also compare E_peak with E_iso, and for those bursts for which a jet break was observed in the afterglow we can derive Eg and test the relationship between E_peak and E_γ . For all bursts we can derive durations and hardness ratios from the prompt emission.
