Note: the exposure times ( $t_{\rm exp}$), filtered for background flares, and the effective exposures ( $t_{\rm eff}$) on XMM J1046, accounting for vignetting, are reported; $\theta$ is the source off-axis angle. Net source photons and the on-axis count rates are in the 0.15-3 keV (XMM-Newton) and 0.5-3 keV (Chandra) energy bands.
