Notes.

(1)

Hardness ratio as defined in the text.

(2)

Temperature(s) or photon index resulting from a MEKAL or power-law model fit to the spectra; depending on the statistical quality of the thermal spectra, the number of temperature components varies.

(3)

Unabsorbed flux in the 0.5–10.0 keV band (×10-13 erg cm-2 s-1). The flux is derived from spectral fitting or, for fainter sources, by scaling an assumed spectrum with the count-rate depending on the source class (see text).

(4)

J magnitude from the 2MASS catalog in cases where a counterpart was found within 2 arcsec of the X-ray source.

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.
