J/A+A/525/A53       GBM parameters for detected FERMI bursts     (Guetta+, 2011)

FERMI constraints on the high energy, ∼1 GeV, emission of long gamma ray bursts. Guetta D., Pian E., Waxman E. <Astron. Astrophys., 525, A53 (2011)> =2011A&A...525A..53G
ADC_Keywords: Gamma rays Keywords: gamma rays: general Abstract: We investigate the constraints imposed on the luminosity function (LF) of long duration gamma ray bursts (LGRBs) by the flux distribution of bursts detected by the GBM at ∼1MeV, and the implications of the non detection of the vast majority, ∼95%, of the LGRBs at higher energy, ∼1GeV, by the LAT detector.

1- 7 A7 --- GRB GRB name 9- 14 F6.1 s T90 Duration of the GRB 16- 23 E8.3 mJ/m2 Fluence ?=- GRB fluence in the energy interval specified in "Band" (in erg/cm2) 25- 32 E8.3 ph/s/cm2 PF ?=- GRB peak flux 34- 35 I2 keV Band1 ?=- Energy band for the fluence determination 36- 40 I5 keV Band2 ?=- Energy band for the fluence determination 42- 47 A6 --- Function Method used to fit the spectra (1) 49- 54 F6.1 keV Ep ?=- Peak energy (2) 56- 61 F6.2 --- alpha ?=- alpha spectral index (2) 63- 67 F5.2 --- beta ?=- beta spectral index (2) 69- 73 F5.1 deg theta ?=- Angle, from the LAT boresight 75 I1 --- LAT [0/1] LAT detection (1=YES, 0=NO) 77- 84 E8.3 mW/m2 f(1Mev) ?=0 The flux (νfν) at ∼1MeV 86- 93 E8.2 mW/m2 f(100MeV) ?=0 The flux (νfν) at ∼100MeV obtained by extrapolating to high energy the ∼1MeV spectrum 95- 98 F4.2 --- z ?=- Redshift
Note (1): Methods as follows: Band = broken power law SPL = single power law PL+HEC = power law and exponential cutoff Note (2): the "Band" law fits the spectrum with * dN/dE ∝ Eα for E<Ep * dN/dE ∝ Eβ for E>Ep
