Notes. Swift observations 00032727002 and 00032727003, 00032727024 and 00010039001, 00032727025 and 00010039002, 00032727026 and 00010039003, 00032727027 and 00010039004, and 00032727028 and 00010039005 were taken during the same spacecraft orbit, hence their data were combined (which is identified by a “+” sign in the ObsID column). No count rate is provided for Swift dataset 00032727001 because of centroiding problems during the light curve generation; however, its associated spectrum could be extracted (see Table 4). EL and HR stand for actual exposure length (i.e. after flare filtering and considering a live time of 71%) and hardness ratio, respectively, while S, M, and H correspond to soft (0.3–0.6 keV), medium (0.6–1.2 keV), and hard (1.2–4.0 keV) energy bands. VI is a variability index, expressed as (max−min)/(max + min) – it thus compares the amplitude of the count rate variation (i.e. half the peak-to-peak variation amplitude) to the mean. To correct for measurement noise, the fractional variability amplitudes Fvar, defined as where Xm = ∑ Xi/N, S2 = ∑ (Xi−Xm)2/ (N−1), and , are also shown. These amplitudes are provided for each XMM-Newton exposure and for each cycle observed by Swift, except if the measurement noise exceeds the variance () for Fvar.

Current usage metrics show cumulative count of Article Views (full-text article views including HTML views, PDF and ePub downloads, according to the available data) and Abstracts Views on Vision4Press platform.

Data correspond to usage on the plateform after 2015. The current usage metrics is available 48-96 hours after online publication and is updated daily on week days.

Initial download of the metrics may take a while.
