\begin{table}%t7 %\centering \par \caption{Maxima and minima of the best-fit models of the November 14 and of the December 1st flares in three different energy bands. The November 14 and the December~1st light curves are binned in 500~s and 200~s intervals, respectively. For the November 14~observation we report also the best-fit e-folding time of the exponential decay model. For the December observation we give the start and stop time of the flare and the flare peak (using two different models, see text). In Cols.~5 and~6 we report the delays between the features of the medium [0.8--2.4]~keV (Col.~5) and the hard [2.4--10]~keV (Col.~6) light curves with respect to those of the soft [0.2--0.8]~keV light curve.\label{flarefit-lags}} \begin{tabular}{cccccc} \hline\hline \multicolumn{6}{c}{14 November}\\ \hline Feature & \multicolumn{3}{c}{Time} & \multicolumn{2}{c}{Lag} \\ & [0.2--0.8] keV & [0.8--2.4] keV & [2.4--10] keV & $t_2-t_1$ & $t_3-t_1$ \\ & (s) & (s) & (s) & (s) & (s) \\ \hline Peak 1 & $\rm 6990^{+300}_{-330}$ & $\rm 6810^{+240}_{-270}$ & $\rm 6980^{+340}_{-400}$ & $\rm -180^{+380}_{-430}$ & $\rm -10^{+450}_{-520}$ \\ Peak 2 & $\rm 20~220^{+250}_{-260}$ & $\rm 20~330^{+160}_{-170}$ & $\rm 20~470^{+160}_{-180}$ & $\rm +110^{+300}_{-310}$ & $\rm +250^{+300}_{-320}$ \\ Peak 3.1 & $\rm 36~360^{+330}_{-430}$ & $\rm 36~220^{+240}_{-640}$ & $\rm 36~550^{+220}_{-410}$ & $\rm -140^{+410}_{-770}$ & $\rm +190^{+400}_{-590}$ \\ $\sigma_1$ & $\rm 25~170^{+980}_{-910}$ & $\rm 16~260^{+880}_{-810}$ & $\rm 9560^{+800}_{-680}$ \\ Peak 3.2 & $41~040\pm220$ & $40~860\pm130$ & $41~000\pm200$ & $-140\pm260$ & $-40\pm300$ \\ Peak 4 & $\rm 62~680^{+670}_{-560}$ & $\rm 62~860^{+530}_{-480}$ & $62~670\pm290$ & $\rm +180^{+850}_{-740}$ & $\rm -10^{+730}_{-630}$ \\ \hline \hline \multicolumn{6}{c}{1 December}\\ \hline Flare start & $790$ & $1210$ & $1550$ & $+420$ & $+760$ \\ Flare peak & $6810$ & $7470$ & $7950$ & $+660$ & $+1140$ \\ Peak (Gauss.) & $6760\pm100$ & $7430\pm80$ & $8010\pm160$ & $+670\pm130$ & $+1250\pm180$\\ Flare end & $13490$ & $13610$ & $13510$ & $+120$ & $+10$ \\ \hline \end{tabular} \end{table}
