Abstract:
We present a systematic spectral analysis of 350 bright gamma-ray
bursts (GRBs) observed with the Burst and Transient Source Experiment
(BATSE; 30keV-2MeV) with high temporal and spectral resolution. Our
sample was selected from the complete set of 2704 BATSE GRBs based on
their energy fluence or peak photon flux values to assure good
statistics and included 17 short GRBs. To obtain well-constrained
spectral parameters, several photon models were used to fit each
spectrum.

Note (2): the model names are as follows:
PWRL = Power-Law Model: a single power law with two free parameters
A and λ as:
f(E) = A (E/Eb)λ
BAND = empirical GRB model by Band et al., 1993ApJ...413..281B 1993ApJ...413..281B
with 2 exponents α and β for low/high energy
COMP = Comptonized Model, where
f(E) = A (E/Eb)α exp((-E(2+α))/Ep)
SBPL = Smoothly Broken Power Law, with power coefficients
λ1 for the low energies and λ2
for high energies; the break scale Λ is the
fifth parameter of this model.
Note (3): Fitted Epeak for BAND or COMP, and calculated Ep for SBPL.
Note (4): pow1 is λ for PWRL, α for BAND or COMP, and
λ1 for SBPL; pow2 is β for BAND and λ2 for SBPL.
Note (5): Fitted Eb for SBPL, and calculated Eb for BAND.
Note (6): Small χ2 values are expected for calibration bursts by
default.
