Note: spectra extracted from these observations are fit with an absorbed power law (absorption column density $N_{\rm H}$ and photon index $\Gamma$). $F_{\rm obs}$ is the. XRT/PC or XRT/WT (BAT) absorbed flux in the 0.3-10 keV (15-80 keV) energy band. EXP indicates the total exposure time of each observation.
(Swift observations comprise several snapshots and are not continuous pointings at the source). a 3$\sigma $ upper limit. b C-statistic has been used to fit the spectrum. c In this case the BAT flux is in the energy range 15-50 keV.
