\tablefoot{The first 3 columns give the day of the burst, its start time (trigger numbers in brackets) and time since the last observed burst~($\Delta t$). For the burst parameters~($t_{\rm rise}$, $t_{\rm decay}$, $F_{\rm peak}$, $E_{\rm b}$, $\tau$ and $t_{\rm dur}$) see Sect.~\ref{xrbprop}; $\chi^2_{\rm red}$/d.o.f. gives the goodness of the fit of the decay to an exponential and the degrees of freedom~(d.o.f.). The rest of the columns refer to the average ASM persistent emission  (Sect.~\ref{xray_spectra}): time span over which it was averaged, goodness of fit of the emission to a power~law and d.o.f. ($\chi^2_{\rm red~,pl}$/d.o.f.) and parameters~$\gamma_{\rm pl}$ and~$N_{\rm pl}$. $F_{\rm X,l}$, $F_{\rm X}$ and $F_{\rm X,bol}$ refer to literature$^a$~values of the absorbed persistent flux in various energy bands before 1994$^{d-k}$, and the unabsorbed persistent fluxes at 2$-$10~keV and 0.1$-$200~keV after~1994, respectively.
