Notes. Stellar parameters L∗, R∗, M∗, ST and extinction are taken from Luhman (2004, 2007), unless explicitly noted.

(a)

Coordinates from the 2MASS catalogue.

(b)

Luminosity computed by integrating the spectral energy distribution between 1 and 70/100 μm, using 2MASS and Spitzer measurements corrected for extinction.

(c)

Obtained from AJ given by Luhman (2007).

(d)

K-band magnitude from 2MASS.

(e)

Spectral index computed from 2 to 12 μm  (see Luhman et al. 2008).

(f)

Extinction estimate from the (J − H)-(H − K) colour–colour diagram.

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.
