cds-question@unistra.frgamma-ray-astronomyx-ray-sourcesredshiftedX-ray flares are generally supposed to be produced by later activities of the central engine, and may share a similar physical origin with the prompt emission of gamma-ray bursts (GRBs). In this paper, we have analyzed all significant X-ray flares from the GRBs observed by Swift from 2005 April to 2015 March. The catalog contains 468 bright X-ray flares, including 200 flares with redshifts. We obtain the fitting results of X-ray flares, such as start time, peak time, duration, peak flux, fluence, peak luminosity, and mean luminosity. The peak luminosity decreases with peak time, following a power-law behavior L_p_{propto}T_peak,z_^-1.27^. The flare duration increases with peak time. The 0.3-10keV isotropic energy of the distribution of X-ray flares is a log-normal peaked at 10^51.2^erg. We also study the frequency distributions of flare parameters, including energies, durations, peak fluxes, rise times, decay times, and waiting times. Power-law distributions of energies, durations, peak fluxes, and waiting times are found in GRB X-ray flares and solar flares. These distributions could be well explained by a fractal-diffusive, self-organized criticality model. Some theoretical models based on magnetic reconnection have been proposed to explain X-ray flares. Our result shows that the relativistic jets of GRBs may be dominated by Poynting flux.2016ApJS..224...20Yhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJS/224/20CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/ApJ/800/16 : Swift-XRT long GRB durations (Boer+, 2015)J/A+A/562/A2 : 100-month Swift catalogue of SFXTs (Romano+, 2014)J/A+A/528/A122 : SwiftFT catalog (Puccetti+, 2011)J/MNRAS/397/1177 : Swift-XRT observations of GRBs (Evans+, 2009)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJS/224/20https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJS/224/20http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJS/224/20https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJS/224/20https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJS/224/20http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJS/224/20GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJS/224/20/table1 (Fitting results of X-ray flares for 201 GRBs)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJS/224/20/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJS/224/20/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJS/224/20/table1?GETtext/xml+votable180.050000true34.4675-50.187720.0055555555555555566/186 205 207 314 462 500 550 699 877 908 918 1001 1882 2336 2793 3038 3405 3506 3536 3586 3589 3935 4450 4485 5253 5606 6004 7043 7356 7363 7532 7558 7589 7685 8021 8182 8954 9024 9069 9321 9714 9827 9926 9989 10135 10407 10445 10680 10723 10852 10948 11140 11372 11456 12020 12134 12226 13312 13331 13558 13574 13787 13889 13898 14248 14555 14567 14846 14892 14977 15054 15320 15485 15498 15530 15613 15702 15820 15915 15995 16232 16292 16991 17279 17316 17453 17721 17980 18258 18494 18728 18777 18910 18930 19049 19168 19731 20191 20360 20655 20668 20710 21284 21903 21962 22559 22580 22624 23138 24007 24036 24041 25131 25293 25733 25901 25926 25946 26503 27085 27933 28032 28033 28496 28726 28831 28863 29685 29731 29816 30088 30235 30553 30692 31028 31092 31143 31281 31385 31547 31700 31847 31934 32234 32676 33265 33278 33841 33977 34435 34461 34465 34590 34788 34832 34949 35045 35088 35256 35393 36066 36297 36528 37324 37383 37459 37675 37737 37830 38046 38504 39076 39432 39881 39912 40167 40272 40433 40559 40778 41020 41989 42952 43193 43920 44419 44822 45008 45088 45402 45729 45836 46395 46989 47162 47245 48189 48371 48458 49034https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJS/224/20?format=asciiGamma-rayX-raydefaultJ/ApJS/224/20/table1Fitting results of X-ray flares for 201 GRBsrecnoRecord number assigned by the VizieR team.
