Notes. The table includes the mean visual magnitude for RR Lyrae stars (Mackey & Gilmore 2003a; Greco et al. 2007), average visual dust extinction Schlegel et al. (1998), spectroscopic metallicities (Letarte et al. 2006; Larsen et al. 2012a), and derived distances. Uncertainties on the adopted distances have been computed taking into account the uncertainties on the variables as listed here. We also give the fraction of the total stellar mass sampled by the 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.
Initial download of the metrics may take a while.
