Notes. Photon indices derived by fitting a power-law to the 0.8–2 keV (ΓS) and 3–7 keV (ΓH) bands after correcting for Galactic absorption. Measurements are given only when the detected source counts exceed 50 cts in the respective bands in order for the spectral slope to have meaningful constraints.
