Notes.
Tycho-2 and IRAS identification, equatorial coordinates from 2MASS, Galactic coordinates and proper motions from Tycho-2; magnitudes and fluxes from catalogues listed in the text; Teff and log g from our SED fits; period and amplitude in the V band from our time-series analysis; and spectral type from our CAFOS observations.
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.
