cds-question@unistra.frgamma-ray-astronomystellar-flaresx-ray-sourcesredshiftedWe present a catalog of 498 flaring periods found in gamma-ray burst (GRB) light curves taken from the online Swift X-Ray Telescope GRB Catalogue (Evans et al. 2007A&A...469..379E, 2009, J/MNRAS/397/1177). We analyzed 680 individual light curves using a flare detection method developed and used on our UV/optical GRB Flare Catalog. This method makes use of the Bayesian Information Criterion to analyze the residuals of fitted GRB light curves and statistically determines the optimal fit to the light curve residuals in an attempt to identify any additional features. These features, which we classify as flares, are identified by iteratively adding additional "breaks" to the light curve. We find evidence of flaring in 326 of the analyzed light curves. For those light curves with flares, we find an average number of ~1.5 flares per GRB. As with the UV/optical, flaring in our sample is generally confined to the first 1000 s of the afterglow, but can be detected to beyond 10^5^ s. Only ~50% of the detected flares follow the "classical" definition of {Delta}t/t<=0.5, with many of the largest flares exceeding this value.2014ApJ...788...30Shttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/788/30CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/MNRAS/397/1177 : Swift-XRT observations of GRBs (Evans+, 2009)J/ApJS/209/20 : Swift GRB catalog with X-ray data (Grupe+, 2013)J/MNRAS/428/729 : GRB Swift X-ray light curves analysis (Margutti+, 2013)J/ApJS/224/20 : 10yr of Swift/XRT obs. of GRBs (Yi+, 2016)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/788/30https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/788/30http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/788/30https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/788/30https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/788/30http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/788/30GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJ/788/30/table1 (X-ray Flares)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/788/30/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/788/30/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/788/30/table1?GETtext/xml+votable180.050000true219.5739583-34.76544720.0055555555555555566/186 205 314 462 500 503 550 646 699 866 877 918 923 1882 2296 2357 2456 2735 2793 2948 3038 3111 3405 3506 3536 3586 3589 3611 3700 3706 3832 3935 4450 4485 5253 5633 5726 6004 6102 6404 6624 6961 7043 7044 7182 7363 7532 7685 8021 8189 8318 8375 8569 8641 8761 8798 8932 8954 9024 9069 9143 9236 9370 9395 9576 9682 9714 9827 9926 9989 10135 10335 10400 10407 10445 10447 10519 10666 10723 10762 10852 10948 11248 11372 12020 12134 12226 13312 13448 13558 13787 13898 14248 14259 14325 14555 14754 14781 14846 14892 14977 15054 15214 15325 15473 15530 15613 15615 15653 15683 15702 15820 15915 15972 15995 16057 16078 16186 16292 16375 16489 16769 16991 17279 17316 17411 17453 17561 17721 17749 17814 17914 17980 18097 18221 18494 18681 18777 18910 18930 18945 19049 19544 19865 19911 20191 20263 20360 20655 20668 21284 21439 21903 22157 22422 22559 22580 22590 22619 22624 22916 23138 23680 24036 24041 25120 25131 25192 25293 25312 25469 25901 25946 26452 26671 26831 27085 27289 27566 27933 28033 28202 28311 28467 28630 28726 28831 28863 28948 29019 29394 29446 29563 29659 29685 30040 30214 30235 30461 30553 30595 30678 30692 31092 31143 31281 31385 31494 31521 31547 31700 31730 31934 31958 31982 32058 32234 32467 32646 32676 32713 32880 33195 33265 33278 33358 33617 33679 33813 33841 34435 34440 34465 34788 34949 35045 35088 35330 35448 35569 35839 36292 36297 36468 36528 37139 37255 37324 37383 37459 37562 37737 37830 38046 38280 38301 38399 38413 38740 39076 39199 39224 39432 39475 39594 39829 39912 40167 40272 40273 40433 40482 40559 40778 41020 41135 41989 42144 42319 42473 42524 42545 42611 42865 42901 42971 43045 43193 43201 43270 43280 43920 44125 44160 44419 44436 44493 44720 44822 45008 45088 45361 45399 45401 45422 45483 45561 45836 46002 46022 46218 46594 46953 47162 47436 47632 47740 47911 47991 48189 48422 48458 49034https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJ/788/30?format=asciiGamma-rayX-rayOpticaldefaultJ/ApJ/788/30/table1X-ray FlaresFP[Y/N] Flaring Period observed; Y/Nmeta.code;obscharrecnoRecord number assigned by the VizieR team.
