1 The X-ray luminosity refers to the bolometric band from 0.1-12 keV.

† System is a confirmed period-bouncer.

* System has been confirmed as a new period-bouncer using eROSITA selection cuts. See Sect. 6 for a discussion of these 7 systems.

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.
