Notes:

• The ASCII lightcurve files have five columns: time since trigger followed by counts/bin in the four Fregate bands (A=7-40 keV, B=7-80 keV, C=30-400 keV, D=>400 keV).
• The values given above reflect the HETE team's best analyses at the time of the creation of this page. Certain values may change as further analyses are performed.
• Redshifts are taken from Jochen Greiner's web page.
• The values of Epeak and fluence are given as a guide; papers giving fuller results of the analyses of these bursts will be posted to astro-ph and this page soon.
• Further details on the data on this page will be posted soon.

Answers to questions from outside the HETE team

Since the publication of these lightcurve data, questions have been put to the HETE team on various points. This list will be modified from time to time to make the questions and answers to them available to all who are interested. Please check this list from time to time.

• What is the value of S(2-30 keV)/S(30-400 keV) for GRB 030429?
  S(2-30 keV) is 4.7 +/- 0.5 x 10^-7 erg/cm2, S(30-400 keV) is 3.8 +/- 1.3 x 10^-7 erg/cm2, so S(2-30 keV)/S(30-400 keV) is 1.24 +/- 0.44.
• What is the fifth column in the ASCII lightcurve table?
  The fifth column is band D, counts with E>400 keV.
• I've seen band A described as 7-30 keV and 7-40 keV: what is the correct bandpass?
  The correct bandpass is 7-40 keV.
• I note that GRB030723 was classified as an X-ray rich GRB: is it not an XRF after all? What was E_peak for 030723?
  The situation of GRB030723 is similar to GRB020903: the best fit spectral model is simple power-law. The Epeak energy can be estimated using the constrained Band function: it is < 11.3 keV in 99.7% upper limit. When we used a cutoff power-law model for calculating the X/gamma fluence ratio, S(X)/S(gamma) = 8.1; thus GRB030723 is an XRF.
• What is the value of S(2-30 keV)/S(30-400 keV) for GRB 030528? What is the value of pseudo-Z for this burst?
  S(2-30 keV) is 6.3 +/- 0.3 x 10^-6 erg/cm2, S(30-400 keV) is 5.6 +/- 0.7 x 10^-6 erg/cm2, so S(2-30 keV)/S(30-400 keV) is 1.13 +/- 0.15. The pseudo Z (Atteia 2003) was calculated to be 0.36.
• What are the peak fluxes for GRB 040701, GRB 041006, GRB 050408, and GRB 051022?
  The peak fluxes in the 30-400 keV band are:
  • GRB 040701: 1.16 +/- 0.7 e-8 erg/cm2/s, .09 +/- .05 ph/cm2/s
  • GRB 041006: 1.0 +/- 0.04 e-6 erg/cm2/s, 8.4 +/- .35 ph/cm2/s
  • GRB 050408: 4.8 +/- 0.54 e-7 erg/cm2/s, 4.0 +/- .45 ph/cm2/s
  • GRB 051022: 4.9 +/- 0.09 e-6 erg/cm2/s, 23.8 +/- 1.24 ph/cm2/s
  These results are preliminary: more refined results will appear in Donaghy et al (in preparation).
