Notes. Sampling refers to the targeted cadence, not counting the seasonal gaps. The number of epochs (#obs), median seeing, airmass and total exposure time are computed from the epochs used in the light curves presented in Fig. 2, which discard ∼13% of the total number of exposures for each data set (mostly due to bad weather or scheduling conflicts). The distribution in seeing and airmass of each data set is shown in the bottom-right panel of Fig. 2.
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.
