Notes. (1) Identification number in the 20k-zCOSMOS Bright Survey; (2) optical right ascension and (3) declination; (4) redshift; (5) I-band AB magnitude; (6) net (“vignetting-corrected”) exposure time in the Chandra mosaic (ks); (7) X/NeV flux ratio using X-ray aperture photometry from Acis Extract to compute the rest-frame 2–10 keV flux (see Sect. 2 for details). Only one of the sources reported above, zCOSMOS_ID = 813850, has been detected in XMM-COSMOS (XMMID = 60494, detected in the 2–8 keV band at the ≈ 4.8σ level; see Cappelluti et al. 2009; Brusa et al. 2010). We note that this source is just below the detection threshold in the C-COSMOS source catalog.
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.
