Notes. (a)Total ART-XC exposure on the source. (b) ART-XC flux in the 4–12 keV energy band averaged over the three sky surveys, estimated assuming a Crab-like spectrum. (c)eROSITA flux in the 0.3–2.2 keV energy band averaged over the three sky surveys, estimated using the best-fit absorbed power-law spectral models from Table 3. (d)Galactic HI column density from HI4PI Collaboration (2016). The flux errors correspond to the 68% confidence level.
