Notes.

^(a)

The average flare detection efficiency above the corresponding non-flaring level.

^(b)

The flare start and end times are given in hh:mm:ss since the day of the observation start. Flares beginning or ending at the start or stop of the observation lead to a lower limit on the flare duration and a lower or upper limit on the flare mean count rate and mean flux. The flux value of these flares were taken equal to this limit in the flaring rate study.

^(c)

The flare mean count rates are computed after subtraction of the non-flaring level.

^(d)

Mean unabsorbed flux between 2 and 10 keV determined for N_H = 14.3 × 10²² cm^-2 and Γ = 2.

^(e)

For this observation, the Galactic center was observed only with EPIC/pn.

^(f)

For these observations, the Galactic center was observed only with EPIC/MOS1 and 2.

^(g)

The data transfer from XMM-Newton to the Earth during this observation was affected by the GALILEO launch and Early Orbit Phase.

^(h)

Frame window extended mode.

⁽ⁱ⁾

^(j)

^(k)
