SWIFT LGRB PEAK LUMINOITY SAMPLE
The following data sample of 209 bursts is taken from the publication:
Constraining the rate, luminosity function and metallicity dependence of Swift gamma-ray bursts, E. Howell, D. Coward, G. Stratta, B. Gendre and H. Zhou, MNRAS, 444,15 (2014), (please not that the luminosities in the Table A1 of this paper are given wrongly as 1053 rather than 1051 - an erratum is being submitted ). Redshift data is labeled by the technique with which the redshift is obtained: emission (E), absorbtion (A) and photometrically (P). For redshifts determined though multiple criteria, absorbtion takes precedence followed by absorbtion. The observation time data can be used for the waiting time relations given in the same paper and outlined on these pages (see XXX and XXX). Isotropic peak luminosity data is determined from the redshift and peak energy
data with k and bolometric correction terms determined using individual burst spectra. Exhaustive details are outlined in the publication which can be downloaded below.
The authors gratefully achnowledge two sources which made this data possible:
a) Firstly to obtain a selection of
Swift LGRBs, rather than
employing a T90 cut, we use the catagorisations given in
the
Jochen Greiner online catalogue of well localized GRBs. The burst catagorisations and redshift values in this
catalogue are subject to review through recent follow up studies - therefore
we find it a useful resource to isolate a LGRB sample.
b) The spectral parameters catalogued for each
burst are taken from
Butler’s online catalogue of Swift BAT Integrated Spectral Parameters - the peak energy flux data is taken from the same source.
A full description of the data sample can be found in the paper. If you use the data in any study, we would much appreciate it if you could cite the two sources given above as well as ourselves. Cites are given in Bibtex form below as well as links to the paper. Many thanks !
Also, we would appreciate if you could inform us of any errors or inconsistencies rhat you spot. We expect this page to be updated every few months, and also other data to be made available, so you are welcome to come back.
