a Outburst duration in weeks. b Outburst fluency in units of ${\rm erg~cm}^{-2}$ in the 2-10 keV energy band, which was calculated by multiplying the mean unabsorbed outburst flux by the outburst duration. c Estimated long-term averaged accretion rate ( ${\rm M}_{\odot}~{\rm yr}^{-1}$) for a neutron star with $M=1.4~{\rm M_{\odot}}$ and $R=10~{\rm km}$d Estimated long-term averaged accretion rate ( ${\rm M}_{\odot}~{\rm yr}^{-1}$) for a black hole with $M=10~{\rm M_{\odot}}$ and $R=30~{\rm km}$. e AX J1745.6-2901 and GRS 1741.9-2853 both display type-I X-ray bursts and are thus confirmed neutron star systems.
