Notes. The top eight sources have no X-ray detection. The bottom seven sources have X-ray emission, and hence the SED fitted parameters of the B component may be unreliable. ^( † )The ID number from Platais (1992). An extended version of the table, including UVIT photometry and SED fitting parameters, is available at the CDS.

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.
