Notes. Masses and cooling ages (fourth and fifth columns) are calculated from our sequences under the assumption that they are He-core white dwarfs. log g and log Teff values were taken from the tables of Silvotti et al. (2012, first 38 listed objects), Hermes et al. (2013, next 3 listed objects), and Brown et al. (2013, final 17 listed objects). The last two columns list the values as derived from our procedure for quick mass and age determination, see Sect. 4.1.

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.
