\caption{IBIS and SPI spectral properties of GRBs for which Band and quasithermal (PL~+ BB)~models are fit to spectra. Parameters quoted are low energy power-law index,
$\alpha$, high energy power-law index, $\beta$, and break
energy, $E_{0}$, for Band model fits and temperature, \textit{kT} and power-law index,
$\Gamma$ for quasithermal model fits.}
