Notes. X-ray flux and luminosity, in units of 10-13 erg s-1 cm-2 and 1031 erg s-1, respectively, are calculated in the 0.3−10.0 keV energy band. LUV is calculated for the bandwidth of the filter used during the observation (see Figs. 2 and 3) and tabulated in units of 1031 erg s-1 (see Table 3).

(a)

We used E(B − V) = 0.25 (Schmid & Nussbaumer 1993) to calculate the UVOT unabsorbed luminosity.

(b)

We used E(B − V) = 1.18 (Pereira 1995) to calculate the UVOT unabsorbed luminosity.

(c)

We used E(B − V) = 0.92 (Santander-García et al. 2009) to calculate the UVOT unabsorbed luminosity.

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.
