Gamma-ray bursts spectral peak estimator J/MNRAS/407/2075 ivo://CDS.VizieR/J/MNRAS/407/2075 doi:10.26093/cds/vizier.74072075 CDS Shahmoradi A. Nemiroff R.J. 2024-07-12T20:14:30Z 2011-04-11T13:20:53Z CDS support team CDS, Observatoire de Strasbourg, 11 rue de l'Universite, F-67000 Strasbourg, France cds-question@unistra.fr gamma-ray-astronomy Simple hardness ratios are found to be a good estimator for the spectral peak energy in gamma-ray bursts (GRBs). Specifically, a high correlation strength is found between the nuFnu peak in the spectrum of Burst and Transient Source Experiment (BATSE) GRBs, Ep,obs and the hardness of GRBs, inline image, as defined by the fluences in channels 3 and 4, divided by the combined fluences in channels 1 and 2 of the BATSE Large Area Detectors (LADs). The correlation is independent of the type of the burst, whether long-duration GRB (LGRB) or short-duration (SGRB) and remains almost linear over the wide range of the BATSE energy window (20-2000KeV). Based on Bayes theorem and Markov Chain Monte Carlo techniques, we also present multivariate analyses of the observational data while accounting for data truncation and sample incompleteness. Prediction intervals for the proposed inline image relation are derived. Results and further simulations are used to compute Ep,obs estimates for nearly the entire BATSE catalogue: 2130 GRBs. 2010MNRAS.407.2075S https://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/407/2075 Catalog Research IsServedBy TAP VizieR generic service IsServedBy Conesearch service related-to IX/20 : The Fourth BATSE Burst Revised Catalog (Paciesas+ 1999) J/ApJS/166/298 : Spectral cat. of bright BATSE gamma-ray bursts (Kaneko+, 2006) https://cds.unistra.fr/vizier-org/licences_vizier.html https://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/407/2075 https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/407/2075 http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/407/2075 https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/407/2075 https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/407/2075 http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/407/2075 GET text/xml+votable https://tapvizier.cds.unistra.fr/TAPVizieR/tap Cone search capability for table J/MNRAS/407/2075/table1 (*Summary of the spectral properties of 249 BATSE GRBs used to calibrate the linear HRH-EpObs relation in Sect. 2.2.) https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/407/2075/table1? https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/407/2075/table1? http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/407/2075/table1?
