Notes. Columns: (1) source name in the SDSS-DR7 catalogue; (2) redshift from Hewett & Wild (2010) as reported in Shen et al. (2011); (3) bolometric luminosity from Shen et al. (2011), in erg s−1; (4) monochromatic luminosity at rest-frame 2500 Å computed from a custom fit of the optical spectrum (Lusso et al., in prep.), in erg s−1 Hz−1; (5) observation date and time; (6) net exposures for pn and both MOS arrays; (7–9) source net counts in the 0.5–8 keV band, as derived for each EPIC detector from the cleaned event files.
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.
