\caption{Spectral analysis results for GRB~040106 with SPI and IBIS/ISGRI for two~intervals around the prominent peaks of emission. Errors quoted are for 1~parameter of interest at 1$\sigma$~confidence level. Fluxes are quoted for the energy range 20--200~keV. Within the large 
errors on the spectral fits, results are consistent between instruments. }
