Notes. For sources that displayed multiple outbursts, we fitted the different outburst spectra simultaneously with the hydrogen column density tied. The 2006 and 2007 data (discussed by Degenaar & Wijnands 2009) are re-fitted in this work. Fluxes and luminosities are for the 2–10 keV energy band and given in units of 10-12 erg cm-2 s-1 and 1034 erg s-1, respectively. FX,abs and FX,unabs represent the mean absorbed and unabsorbed outburst fluxes, while FX,peak is the unabsorbed peak flux. LX and LX,peak are the average and peak outburst luminosity, respectively. These are calculated from the unabsorbed fluxes by adopting a distance of 7.2 kpc for GRS 1741–2853 and 8 kpc for all other sources. Fluxes for the 2007 activity of XMM J174457–2850.3 were deduced using pimms, for fixed values of NH and Γ.
