Notes. The σ represents the transformation error, and if significant, we add in quadrature the published errors. Equations (10)–(21) were determined from a combination of Johnson - GSC2 transformations derived internally and Tycho - Johnson transformations published in the “Guide to the Tycho-2 Catalog” (Hog et al. 2000, http://www.astro.ku.dk/~erik/Tycho-2/). Equations 41/42 were calculated internally from a GSC23 to 2MASS match. Other equations between 28−57 were taken from Jordi (2012) combined with Høg et al. (2000) and internal transformations where needed.
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.
