Abstract:
To date, the Burst Alert Telescope (BAT) onboard Swift has detected
∼1000 gamma-ray bursts (GRBs), of which ∼360 GRBs have redshift
measurements, ranging from z=0.03 to z=9.38. We present the analyses
of the BAT-detected GRBs for the past ∼11 years up through GRB151027B.
We report summaries of both the temporal and spectral analyses of the
GRB characteristics using event data (i.e., data for each photon
within approximately 250s before and 950s after the BAT trigger time),
and discuss the instrumental sensitivity and selection effects of GRB
detections. We also explore the GRB properties with redshift when
possible. The result summaries and data products are available at
http://swift.gsfc.nasa.gov/results/batgrbcat/index.html. In addition,
we perform searches for GRB emissions before or after the event data
using the BAT survey data. We estimate the false detection rate to be
only one false detection in this sample. There are 15 ultra-long GRBs
(∼2% of the BAT GRBs) in this search with confirmed emission beyond
∼1000s of event data, and only two GRBs (GRB 100316D and GRB 101024A)
with detections in the survey data prior to the starting of event
data.
Description:
In this catalog, we update the results in the BAT2 catalog (Sakamoto+,
2011, J/ApJS/195/2) to include the GRBs detected by BAT after 2009. We
include all the bursts through the 1000th Swift GRB, GRB 151027B,
which was officially announced by the Swift team.
In the third BAT GRB catalog, we include all GRBs that were reported
being seen by Swift/BAT (either triggered onboard or found by ground
analyses, some of which may be motivated by detections from other
instruments).
To make sure the analyses for the new and old bursts are consistent,
we reanalyze all the bursts in the BAT2 catalog as well, using the
same up-to-date software.

Global notes:
Note (G1): The observation ID of the event data used in this analysis is
00"Trid_ID"000. For GRBs found in ground analysis, the ID are
associated with the trigger ID of the failed event data, or the full
observation ID of the event data for the analysis.
Note (G2): Relative to the BAT trigger time.
Note (G3): Either the simple power law model (PL) or cutoff power-law
model (CPL). N/A means not applicable.
