Fig. 6


Present-day mass function of the Hyades between 0.05 and 3 M . This MF is combined from our new TLS survey, the Bouvier et al. (2008) survey and the Prosser & Stauffer database (solid line). The dashed histogram corresponds to the data shown in Bouvier et al. (2008). The data derived from our survey added objects to the Hyades MF in the two lowest mass bins, 0.048–0.12 and 0.12–0.19 M. The error bars take into account the Poissonian error and the photometric uncertainties as well. For comparison, the Pleiades MF (dashed histogram) adopted from Bouvier et al. (2008) is overplotted. Both the TLS and the Pleiades MFs are normalised to the mass distribution of the Prosser & Stauffer database as described in Bouvier et al. (2008).

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.
