cds-question@unistra.frx-ray-sourcesAll of the observations performed with the IBIS telescope onboard the INTEGRAL observatory during the first one and a half years of its in-orbit operation (from February 10, 2003, through July 2, 2004) have been analyzed to find X-ray bursts. The time history of the IBIS/ISGRI total count rate in the energy range 15-25keV revealed 1077 bursts of durations from 5 to 500s with a high statistical significance (over the entire period of observations, only one event could be detected by chance with a probability of 20%). A part from the events associated with cosmic gamma-ray bursts (detected in the field of view or passed through the IBIS shield), solar flares, and activity of the soft gamma repeater SGR 1806-20, we were able to localize 105 bursts and, with one exception, to identify them with previously known persistent or transient X-ray sources (96 were identified with known X-ray bursters). In one case, the burst source was a new burster in a low state that received the name IGR J17364-2711. Basic parameters of the localized bursts and their identifications are presented in the catalog of bursts. Curiously enough, 61 bursts were detected from one X-ray burster, GX 354-0. The statistical distributions of bursts in duration, maximum flux, and recurrence time have been analyzed for this source. Some of the bursts observed with the IBIS/ISGRI telescope were also detected by the JEM-X telescope onboard the INTEGRAL observatory in the standard X-ray energy range 3-20keV.2006PAZh...32..508Chttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/PAZh/32/508CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+A/458/21 : INTEGRAL burst observations of 4U 1728-34 (Falanga+, 2006)J/A+A/411/L59 : INTEGRAL reference catalog (Ebisawa+, 2003)J/A+A/438/1175 : First INTEGRAL SPI-ACS Gamma-Ray Burst Catalogue (Rau+, 2005)J/PAZh/30/589 : Hard X-ray catalog of Sagittarius arm (Molkov+, 2004)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/PAZh/32/508https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/PAZh/32/508http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/PAZh/32/508https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/PAZh/32/508https://vizier.iucaa.in/viz-bin/votable?-source=J/PAZh/32/508http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/PAZh/32/508GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/PAZh/32/508/table2 (X-ray bursts detected by the IBIS/ISGRI telescope in the energy range 15-25 keV in 2003-2004.)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/PAZh/32/508/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/PAZh/32/508/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/PAZh/32/508/table2?GETtext/xml+votable180.050000true262.9891667-33.83472220.0055555555555555566/28808 28825 28827 28835 28857 28860 28896 29514 30299 37732 42140 42159 42387 42446https://cdsarc.cds.unistra.fr/viz-bin/moc/J/PAZh/32/508?format=asciiX-raydefaultJ/PAZh/32/508/table2X-ray bursts detected by the IBIS/ISGRI telescope in the energy range 15-25 keV in 2003-2004.recnoRecord number assigned by the VizieR team.
