Notes. The parameters of the source in each column are determined with the meta-tasks edetect_chain and edetect_stack (EPIC, 0.2 − 12 keV). Errors are 1σ statistical uncertainties.

(⋆)

Likelihood of detection.

(†)

Coordinates of the target, corrected for the astrometry with the SAS task eposcorr.

(‡)

Positional offsets in each coordinate determined for the astrometry (see text; for details).

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.
