Notes. (a) Boldface in ID indicates X-ray counterparts from Muno et al. (2009).(b) Maximum value obtained from ∆S/σ in any band.(c) Spectral index’s weighted mean.(d) Value obtained from Eq. (3). Uncertainties were derived using standard error propagation. (e) Spectral type from Clark et al. (2018b) or Dong et al. (2011).(f) Source classification: pCWB = primary CWB candidate, sCWB = secondary CWB candidate, Th. = thermal source, a = ambiguous 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.
