Notes. (1) ID, (2) RA, and (3) Dec from Hill et al. (2020) of the detected X-ray sources; (4) soft-band, (5) hard-band, and (6) full-band net counts; (7) hardness ratio and (8) corresponding effective photon index; (9) column density; (10) full-band flux; (11) intrinsic luminosity. The column density, flux, and luminosity of C1 are derived via a spectral analysis (Sect. 3.1), whereas these quantities are based on the hardness ratio for C6 (Sect. 3.3).
