Notes.

(a)

Stars labelled DM, LOri and LOri-SOC are from Dolan & Mathieu (1999), Barrado y Navascués et al. (2004), and Bouy et al. (2009), respectively. The GSC and 2MASS identifications correspond to the stars labelled c, d, e, g, and Ton 72 in Murdin & Penston (1977), respectively.

(b)

MOS-equivalent count rates in the 0.3−7.8 keV band; upper limits higher than 2 cts/ks are overestimated due to close bright sources.

(c)

X-ray luminosity in the 0.3−8 keV band.

(d)

Disc classification from Barrado y Navascués et al. (2007) and Hernández et al. (2009); for Class II or EV stars we also indicate whether there is spectroscopic evidence for accretion (a) or not (n).

(e)

An “s” in this column indicates spectroscopically-confirmed members (i.e. objects with spectroscopic youth features and radial velocity consistent with membership).

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.
