Notes.

(a)

XRT observation ID as in Table 1.

(b)

The radius of the disk is estimated as described in the notes of Table 1.

(c)

The value of Γ was fixed to that of the averaged broad-band spectrum (Fig. 3).

(d)

The observation was divided into two snapshots that we analyzed separately.

(e)

As in Table 1.

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.
