Cline\non behalf of the Konus-Wind team, report:\n\nThe long-duration, intense GRB 160101A\n(MAXI detection: Itoh et al., GCN Circ. 18793;\nFermi GBM detection: Veres, GCN Circ. 18796)\ntriggered Konus-Wind at T0=2631.931 s UT (00:43:51.931).\n\nThe burst light curve shows a single pulse\nwith a total duration of ~4.6 s.\nThe emission is seen up to ~5 MeV.\n\nThe Konus-Wind light curve of this GRB is available at\nhttp://www.ioffe.ru/LEA/GRBs/GRB160101_T02631/\n\nAs observed by Konus-Wind, the burst\nhad a fluence of 1.47(-0.17,+0.21)x10^-5 erg/cm2,\nand a 64-ms peak flux, measured from T0+0.214 s,\nof 1.18(-0.30,+0.35)x10^-5 erg/cm2/s\n(both in the 20 keV - 10 MeV energy range).\n\nThe time-averaged spectrum of the burst\n(measured from T0 to T0+8.448 s)\nis best fit in the 20 keV - 10 MeV range\nby the GRB (Band) model with the following parameters:\nthe low-energy photon index alpha = -1.19(-0.19,+0.25),\nthe high energy photon index beta = -2.86(-7.14,+0.38),\nthe peak energy 143(-19,+20) keV\n(chi2 = 103/83 dof).\n\nThe spectrum near the maximum count rate\n(measured from T0 to T0+0.256 s)\nis best fit in the 20 keV - 5 MeV range\nby a power law with exponential cutoff model:\ndN/dE ~ (E^alpha)*exp(-E*(2+alpha)/Ep)\nwith  alpha = -1.06(-0.23,+0.27)\nand Ep = 612(-175,+321) keV (chi2 = 26/41 dof).\nFitting by a GRB (Band) model yields the same alpha and Ep,\nand an upper limit on the high energy photon index: beta <-2.0\n(chi2 = 26/40 dof).\n\nAll the quoted errors are at the 90% confidence level.\nAll the quoted values are preliminary.",
