Notes.
(d)
X: X-ray source; NaI: shallow Na I doublet; IRex: exhibiting infrared excess; Hα: Hα compatible with accretion. X-ray detections are from Alcala et al. (1995), classified as WTTS therein.
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.
