Notes. Columns 1, 2, and 3 list different identifiers: Tycho2 (Høg et al. 2000), GCVS, HD, BD, and Catalog of Galactic S stars (CGSS) entry number. Columns 4, 5, 6, and 7 list spectral type, V magnitude, V –K colour, and K magnitude, respectively, extracted from the SIMBAD Astronomical Database (Wenger et al. 2000). Column 8 lists the GDR2 parallax and its error. Columns 9 and 10 compare the distances obtained by simple inversion of the parallax and by Bayesian inference (Bailer-Jones et al. 2018), the latter including the 1σ error bar. The reddenning EB−V has been obtained from the Gontcharov (2012) extinction maps. Columns 12 and 13 list the K-[12] and K-[25] from the IRAS Point Source Catalog and 2MASS K magnitude (Skrutskie et al. 2006).
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.
