Notes.

(†)

The uncertainties in the spectro-polarimetric parameters, computed using the error command in XSPEC, are provided at the 68.3% (1σ) confidence level (Δχ2 = 1 for one parameter of interest). The right two columns give PDs and PAs estimated with the pcube algorithm and the uncertainties given at the 1σ confidence level. The PA cannot be confined within the 1σ confidence level; therefore, we presented the most probable value instead.

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.
