Cline\non behalf of the Konus-Wind team, report:\n\nThe long-duration, intense GRB 170101A\n(Swift-BAT trigger #729293: Lien  et al., GCN 20349;\nBarthelmy et al., GCN 20353;\nPOLAR observation: Li et al., GCN 20355;\nLomonosov BDRG observation: Bogomolov et al., GCN 20359)\ntriggered Konus-Wind at T0=8757.802 s UT (02:25:57.802).\n\nThe burst light curve shows a single FRED-like pulse\nwith a total duration of ~4 s.\nThe emission is seen up to ~10 MeV.\n\nAs observed by Konus-Wind, the burst\nhad a fluence of 1.35(-0.18,+0.20)x10^-5 erg/cm2,\nand a 64-ms peak energy flux, measured from T0+0.264 s,\nof 1.86(-0.23,+0.24)x10^-5 erg/cm2/s\n(both in the 20 keV - 10 MeV energy range).\n\nThe time-integrated spectrum of the burst\n(measured from T0 to T0+9.472 s)\nis best fit in the 20 keV - 15 MeV range\nby the GRB (Band) model with the following parameters:\nthe low-energy photon index alpha = -1.44(-0.13,+0.17),\nthe high energy photon index beta = -2.49(-0.65,+0.23),\nthe peak energy Ep = 123(-21,+23) keV,\nchi2 = 101/97 dof.\n\nThe spectrum near the peak count rate\n(measured from T0 to T0+1.280 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 = -1.07(-0.15,+0.17),\nthe high energy photon index beta = -2.48(-0.22,+0.14),\nthe peak energy Ep = 124(-15,+18) keV,\nchi2 = 57/56 dof.\n\nThe Konus-Wind light curve of this GRB is available at\nhttp://www.ioffe.ru/LEA/GRBs/GRB170101_T08757/\n\nAll the quoted errors are at the 90% confidence level.\nAll the quoted values are preliminary.",
