Notes. The modified Julian and civil dates of the particular period are given in Cols. 2 and 3, respectively. Columns 4–7 show maximum 0.3–10 keV count rate (in cts s−1), maximum-to-minimum rate ratio, mean rate and fractional variability amplitude, respectively. Next we show maximum unabsorbed flux (in 10−11erg cm−2s−1), maximum-to-minimum flux ratio, mean flux, and fractional amplitude in the 0.3–2 keV (Cols. 8–11) and 2–10keV (Cols. 12–15) bands; maximum unabsorbed flux (in mJy), maximum-to-minimum flux ratio and fractional amplitude in the bands V (Cols. 17–20) and UVW2 (Cols. 21–24).
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.
