Notes. Multiwavelength classification of the ten counterparts with available spectra in the SDSS. There are three sources with the same 3PBC name, each corresponding to a different Swift-XRT soft X-ray detection. We omitted the “3PBC” in each of the source names to keep the table size manageable.

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.
