VOEvent alerts produced from transient detections resulting from
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).
