Notes. All coordinates are given in J2000. For each XGPS-id source, we list the corresponding XGPS-I entry in Hands et al. (2004), the matching 2XMM entry and its combined multi-detection coordinates (when available) and the position of the optical identification. The 90% confidence error radius, r90, is that of the 2XMM entry, while a constant value of 4″ is assumed for XGPS-I only entries (Hands et al. 2004). d x-o is the offset of the proposed optical counterpart from the 2XMM (or XGPS-I) position. MOS count rates refer to the broad (0.4–6.0 keV) band and the hardness ratios are those of the original XGPS processing. In the Class column, AC stands for active coronae. R magnitudes are extracted from the optical catalogue identifications, apart from sources 9, 10, 13, 15 and 24 for which R is estimated from the flux calibrated spectra.

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.
