team report:
The long GRB 101114A discovered in BAT ground analysis (Sakamoto et al.,
GCN 11405) was detected by Konus-Wind in the waiting mode.
The burst light curve shows a rather bright pulse at ~T0(BAT) preceded
by two weak pulses at ~T0(BAT)-100 s and ~T0(BAT)-50 s. The total burst
duration is ~110 s.
As observed by Konus-Wind, the burst had a fluence of (4.7 +/-
2.4)x10^-6 erg/cm2 (in the 20 - 1200 keV energy range).
Modeling the K-W 3-channel spectrum of the main pulse (accumulated from
T0-2.2 s to T0+6.6 s) by a power law with exponential cutoff model:
dN/dE ~ (E^alpha)*exp(-E*(2+alpha)/Ep)
yields alpha = -1.15 +/- 0.29, Ep = 296 +/- 129 keV.
All the quoted errors are estimated at the 1 sigma confidence level.
