observations with the NASA Neil Gehrels Swift Observatory and the
Burst Alert Telescope. Events should be reported within tens to of
seconds to hours; expect about 3 events per week, where most events
correspond to either gamma ray burst, or other transient.

Stream giving alerts and localizations for hard X-ray/gamma-ray
transients beginning with a detection(SWIFT_BAT_GRB_ALERT), lightcurve
('SWIFT_BAT_GRB_LC') and processed light curve
(SWIFT_BAT_GRB_LC_PROC), whether or not the position was acquired
(SWIFT_BAT_GRB_POS_ACK) or not acquired (SWIFT_BAT_GRB_POS_NACK), and
the scaled map image reconstruction (SWIFT_BAT_SCALEDMAP). Observatory
alerts about automated decisions of whether or not to slew to the
detected transient are also included (SWIFT_FOM_OBS).</description><source format="bibcode">2004ApJ...611.1005G</source><referenceURL>http://dc.g-vo.org/std/gcn-swift-bat/swift/info</referenceURL><contentLevel>Research</contentLevel></content><rights>public</rights><capability standardID="ivo://ivoa.net/std/voevent"><interface role="std" standardID="ivo://ivoa.net/std/voevent#acc-kafka" xsi:type="voe:StreamEndpoint"><accessURL use="full">x-kafka://kafka.gcn.nasa.gov?topic=gcn.classic.voevent.SWIFT_BAT_GRB_ALERT</accessURL></interface></capability><capability standardID="ivo://ivoa.net/std/voevent"><interface role="std" standardID="ivo://ivoa.net/std/voevent#acc-kafka" xsi:type="voe:StreamEndpoint"><accessURL use="full">x-kafka://kafka.gcn.nasa.gov?topic=gcn.classic.voevent.SWIFT_BAT_GRB_LC</accessURL></interface></capability><capability standardID="ivo://ivoa.net/std/voevent"><interface role="std" standardID="ivo://ivoa.net/std/voevent#acc-kafka" xsi:type="voe:StreamEndpoint"><accessURL use="full">x-kafka://kafka.gcn.nasa.gov?topic=gcn.classic.voevent.SWIFT_BAT_GRB_LC_PROC</accessURL></interface></capability><capability standardID="ivo://ivoa.net/std/voevent"><interface role="std" standardID="ivo://ivoa.net/std/voevent#acc-kafka" xsi:type="voe:StreamEndpoint"><accessURL use="full">x-kafka://kafka.gcn.nasa.gov?topic=gcn.classic.voevent.SWIFT_BAT_GRB_POS_ACK</accessURL></interface></capability><capability standardID="ivo://ivoa.net/std/voevent"><interface role="std" standardID="ivo://ivoa.net/std/voevent#acc-kafka" xsi:type="voe:StreamEndpoint"><accessURL use="full">x-kafka://kafka.gcn.nasa.gov?topic=gcn.classic.voevent.SWIFT_BAT_GRB_POS_NACK</accessURL></interface></capability><capability standardID="ivo://ivoa.net/std/voevent"><interface role="std" standardID="ivo://ivoa.net/std/voevent#acc-kafka" xsi:type="voe:StreamEndpoint"><accessURL use="full">x-kafka://kafka.gcn.nasa.gov?topic=gcn.classic.voevent.SWIFT_FOM_OBS</accessURL></interface></capability><capability standardID="ivo://ivoa.net/std/voevent"><interface role="std" standardID="ivo://ivoa.net/std/voevent#acc-kafka" xsi:type="voe:StreamEndpoint"><accessURL use="full">x-kafka://kafka.gcn.nasa.gov?topic=gcn.classic.voevent.SWIFT_BAT_SCALEDMAP</accessURL></interface></capability><capability><description>A browser-based archive of the events recorded.</description><interface xsi:type="vr:WebBrowser"><accessURL use="full">https://gcn.gsfc.nasa.gov/swift_grbs.html</accessURL></interface></capability><capability standardID="ivo://ivoa.net/std/VOSI#capabilities"><interface role="std" xsi:type="vs:ParamHTTP"><accessURL use="full">http://dc.g-vo.org/std/gcn-swift-bat/swift/capabilities</accessURL><mirrorURL>https://dc.g-vo.org/std/gcn-swift-bat/swift/capabilities</mirrorURL></interface></capability><facility>Neil Gehrels Swift Observatory</facility><instrument>Swift Burst Alert Telescope BAT</instrument><coverage><spatial>0/0-11</spatial><temporal>53329 64328</temporal><spectral>2.403264931e-15 2.403264931e-14</spectral><footprint ivo-id="ivo://ivoa.net/std/moc">http://dc.g-vo.org/std/gcn-swift-bat/swift/coverage</footprint><waveband>Hard X-ray</waveband></coverage></ri:Resource>
