Notes.

^(a)

Integrated with one day time interval executed in PC mode with exposure time longer than 200 s.

^(b)

Median count rate in the total 0.3 − 10 keV band.

^(c)

Median Absolute Deviation about the median count rate.

^(d)

Blazar associated with the IceCube high-energy neutrino IC170922 and other IceCube neutrinos (Padovani et al. 2018).
