cds-question@unistra.frgamma-ray-astronomyWe present a new technique to calculate the spectral lags of {gamma}-ray bursts (GRBs). Unlike previous processing methods, we first smooth the light curves of {gamma}-ray bursts in high- and low-energy bands using the "Loess" filter, then we directly define the spectral lags as such to maximize the cross-correlation function (CCF) between two smoothed light curves.2012PASP..124..297Lhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/PASP/124/297CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/ApJS/169/62 : GRB database of spectral lags (Hakkila+, 2007)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/PASP/124/297https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/PASP/124/297http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/PASP/124/297https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/PASP/124/297https://vizier.iucaa.in/viz-bin/votable?-source=J/PASP/124/297http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/PASP/124/297GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/PASP/124/297/Glags (Spectral lags of GRBs)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/PASP/124/297/Glags?https://vizier.iucaa.in/viz-bin/conesearch/J/PASP/124/297/Glags?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/PASP/124/297/Glags?GETtext/xml+votable180.050000true49.7125-46.39544720.0055555555555555566/500 503 646 918 1102 1507 2044 2315 2925 3586 3659 3700 3706 3894 4323 4450 4868 5376 5625 5840 5941 6261 7518 8798 9370 9750 9926 9989 10094 10447 10519 11657 12287 13363 13694 14781 14977 15513 15913 15915 16282 17733 18777 19164 19544 19890 20030 20191 20668 21360 21903 21915 22590 22624 23052 23138 23680 25174 25529 27566 27906 27911 27933 27962 28063 28467 28729 30385 30471 30557 31185 31281 31385 31494 31700 31730 33004 33323 33525 33735 33845 34440 35045 35566 35615 35633 35702 36074 36460 36610 37071 37383 38280 39076 39374 39475 39553 39829 40167 40249 40433 41755 42840 43045 43280 44021 44793 44822 45180 45205 45510 45548 45938 46022 46218 47031 48054 48447 49004https://cdsarc.cds.unistra.fr/viz-bin/moc/J/PASP/124/297?format=asciiGamma-raydefaultJ/PASP/124/297/GlagsSpectral lags of GRBsrecnoRecord number assigned by the VizieR team.
