The authors have studied statistically with respect to duration and hardness ratio a sample of 427 gamma-ray bursts (GRBs) measured by the Ramaty High Energy Solar Spectroscopic Imager (RHESSI) satellite, a NASA Small Explorer satellite designed to study hard X-rays and gamma-rays from solar flares (Lin et al., 2002, Sol. Phys., 210, 3). Standard statistical tests were used, such as chi<sup>2</sup>, F-test, and the maximum likelihood ratio test, to compare the number of GRB groups in the RHESSI database with that of the BATSE database. The authors used the RHESSI GRB Catalog (Wigger et al., 2008, <a href="http://grb.web.psi.ch/">http://grb.web.psi.ch/</a>;) and the Cosmic Burst List (Hurley, 2008, <a href="http://www.ssl.berkeley.edu/ipn3/masterli.html">http://www.ssl.berkeley.edu/ipn3/masterli.html</a>;) to detect 487 GRBs in the RHESSI data over the time period between 2002 February 14 and 2008 April 25. For a deeper analysis, they chose a subset of 427 GRBs with data with a signal-to-noise ratio higher than 6. This table contains this subset. This HEASARC table was created in March, 2010, based on <a href="https://cdsarc.cds.unistra.fr/ftp/cats/J/A+A/498/399">CDS catalog J/A+A/498/399</a> file table7.dat. It was updated in September, 2019, with a minor change to the two GRB 051220 entries. Based on the literature, "A" and "B" suffixes were appended to make the names unique. This is a service provided by NASA HEASARC .
