BAT5BGRBSP - CGRO/BATSE 5B Gamma-Ray Burst Spectral Catalog |
HEASARC Archive |
Overview
The CGRO/BATSE 5B Gamma-Ray Burst Spectral Catalog contains the results of systematic spectral analyses of gamma-ray bursts (GRBs) detected with the Burst and Transient Source Experiment (BATSE) on board the Compton Gamma-Ray Observatory (CGRO) during its entire nine years of operation. This catalog contains two types of spectra extracted from 2,145 GRBs, and fitted with five different spectral models resulting in a compendium of over 19,000 spectra. The models were selected based on their empirical importance to the spectral shape of many GRBs, and the analysis performed was devised to be as thorough and objective as possible. In their paper, the authors describe in detail their procedures and criteria for the analyses, and present the bulk results in the form of parameter distributions. This catalog should be considered an official product from the BATSE Science Team, and the data files containing the complete results are soon to be available from the HEASARC.This table lists all of the spectroscopy results of gamma-ray bursts observed by a subset of the 8 BATSE Large Area Detectors. BATSE consisted, in part, of an array of 8 sodium iodide Large Area Detectors (LADs) which covered the energy range from ~20 keV - 2 MeV. The LAD detectors were placed at each of the eight corners of the CGRO spacecraft with an outward orientation such that the entire sky not occulted by the Eartt was observed. The spectrum files ("scat" files) available as FITS-format data products associated with this catalog provide parameter values and goodness-of-fit measures for different types of spectral fits and models. These fits are performed using 14-channel data, usually 2-second resolution CONT data. There are currently two spectrum categories:
* Peak flux ('pflx') - a single spectrum over a 2.05-second time range at the
peak flux of the burst
* Fluence ('flnc') - a single spectrum over the entire burst duration
The quoted fluxes and fluences are for the 20 keV - 2 MeV energy range,
notice. The scat files have two extensions. The first extension gives
detector-specific information, including photon fluxes and fluences for each
detector, which are provided for each energy channel. The second extension
provides derived quantities such as flux, fluence and model parameters for
the joint fit of all included detectors. The scat files and their
energy-resolved quantities contained in these two extensions will be
available soon in the HEASARC data archive. Quantities derived from these
spectral fits are available in the present table, as described below and in
the Goldstein et al. (2013) reference paper.
The spectra are fit with a number of models, with the signal-to-noise ratio of the spectrum often determining whether a more complex model is statistically favored. The current set is:
* Power law ('plaw'),
* Comptonized (exponentially attenuated power law; 'comp')
* Band ('band')
* Smoothly broken power law ('sbpl')
* Log_10 Gaussian ('glog')
The full details of these models are presented in Section 4 of the reference
paper.
The type of spectrum and spectral model are coded into the parameter names (and the associated file names) using the acronyms given above. Thus for example, the parameters with names beginning with 'flnc_glog' contain the results from fits to the fluence spectra using Log10 Gaussian models. The corresponding spectrum file for the burst with trigger number 105 with the results from a fit to the fluence spectrum using a Log10 Gaussian model is named scat_0105_flnc_glog_v00.fit.
Please note that this table lists the raw results of each spectral fit to each GRB. In cases where the spectral fit failed, the values reported are those that initialized the spectral fit. If the uncertainty on the spectral parameters is reported as zero (no uncertainty), then the fit failed. In a few cases throughout this table, the uncertainties for certain spectral parameters may be reported as '9999.99' which indicates that the uncertainty on that parameter is completely unconstrained. An example of this is when the spectral data from a burst is fitted with a BAND function but is unable to constrain the high-energy index. In this case, the best fit centroid value of the high-energy index parameter is reported, and the '9999.99' value is reported for the uncertainty.

Provenance
This table was created by the HEASARC in November 2013 based on electronic versions of Tables 6 through 10, inclusive, from the reference paper which were obtained from the ApJS web site.Parameters
Trigger_Num
The BATSE trigger designation that is assigned for each new
trigger detected. The naming scheme used is an incrementing trigger number,
where 105 is the minimum and 8121 is the maximum trigger number in this table.
Name
The BATSE burst name. This was not present in the reference paper
tables but was added by the HEASARC using the relevant information in the
BATSEGRB table (see http://heasarc.gsfc.nasa.gov/W3Browse/cgro/batsegrb.html
for more information). Each burst has a unique catalog name. These names may
have a prefix of either "4B" or "GRB". The "4B" prefix means that the burst is
listed in BATSE 4B Catalog, while the "GRB" prefix means that the burst is
listed in the BATSE Current Gamma-Ray Burst Catalog. The prefix is followed by
the "yymmdd" (date) of the burst, where "yymmdd" is the two digit year, two
digit month, and two digit day. An ending hyphen is added when this name is
not unique, i.e., when there were two or more bursts on a particular day.
RA
The Right Ascension of the object that triggered the BATSE instrument in
the selected equinox. This was not present in the reference paper
tables but was added by the HEASARC using the relevant information in the
BATSEGRB table (see http://heasarc.gsfc.nasa.gov/W3Browse/cgro/batsegrb.html
for more information).
Dec
The Declination of the object that triggered the BATSE instrument in
the selected equinox. This was not present in the reference paper
tables but was added by the HEASARC using the relevant information in the
BATSEGRB table (see http://heasarc.gsfc.nasa.gov/W3Browse/cgro/batsegrb.html
for more information).
LII
The Galactic Longitude of the object that triggered the BATSE
instrument.
BII
The Galactic Latitude of the object that triggered the BATSE instrument.
Trigger_Time
The burst trigger time defined as the end of the interval
(64, 256 or 1024 ms) in which the burst triggered the detector. The time
system for the values is UT. This was not present in the reference paper
tables but was added by the HEASARC using the relevant information in the
BATSEGRB table (see http://heasarc.gsfc.nasa.gov/W3Browse/cgro/batsegrb.html
for more information).
Seconds_Trigger
The burst trigger time, in decimal seconds of the day (UT)
on which it occurred. The burst trigger time is the end of the interval (64,
256 or 1024 ms) in which the burst triggered the detector. This was not
present in the reference paper
tables but was added by the HEASARC using the relevant information in the
BATSEGRB table (see http://heasarc.gsfc.nasa.gov/W3Browse/cgro/batsegrb.html
for more information).
T90
The 90% duration of the burst in seconds. T90 measures the duration of
the time interval during which 90% of the total observed counts in the burst
have been detected. The start of the T90 interval is defined by the time at
which 5% of the total counts have been detected, and the end of the T90
interval is defined by the time at which 95% of the total counts have been
detected. This was not present in the reference paper
tables but was added by the HEASARC using the relevant information in the
BATSEGRB table (see http://heasarc.gsfc.nasa.gov/W3Browse/cgro/batsegrb.html
for more information).
T90_Error

present in the reference paper
tables but was added by the HEASARC using the relevant information in the
BATSEGRB table (see http://heasarc.gsfc.nasa.gov/W3Browse/cgro/batsegrb.html
for more information).
Lad_Numbers
The LAD detectors which detected the burst. There were 8
detector modules on CGRO each of which contained a LAD
(numbered 0 through 7). A GRB could illuminate up to 4 detectors
Lad_Data_Type
The LAD data type, 'CONT' or 'MER'. The primary data type
used in this catalog is the 2.048 s resolution CONT data, which provided
semi-continuous count rate and 16 channel spectral coverage during the entire
BATSE lifetime. When CONT data were not available (usually due to data
corruption), the associated MER data were used if possible. The native time
resolution of MER data was 16 ms but only started at trigger time and extended
to less than 200 s after trigger. The energy resolution is the same as CONT
data, so the count rates were binned to 2.048 s in order to be compatible with
CONT data. MER data were used only if a background model could be fit to the
post-burst background and extrapolated through the duration of the burst. MER
data were used for only 15 GRBs in this catalog.
