All Tables

Table 1: Observed properties of 17 GRBs with known redshift. The ten columns give the GRB name, the duration T₉₀ in seconds, the three spectral parameters ( $\alpha , \beta$ , and E₀), the gamma-ray fluence $S_{\rm\gamma }$ in units of 10^-6 erg cm^-2, the spectroscopic redshift z, the pseudo-redshift $\hat{z}$ , the ratio $\hat{z}$ /z, and a reference for the spectral parameters.
Table 2: Observed properties of 18 GRBs with no measured redshift. The eight columns give the name of the GRB, the time of arrival, the duration T₉₀ in seconds, the three spectral parameters ( $\alpha$ , $\beta$ , and E₀), the gamma-ray fluence $S_{\gamma }$ in units of 10^-6 erg cm^-2 in the range 30-400 keV, the pseudo-redshift $\hat{z}$ , and a comment on the eventual detection of an afterglow (XRR stands for X-Ray Rich GRB, OA, XA, and RA, respectively for Optical Afterglow, X-ray Afterglow, and Radio Afterglow).
