Notes.
In the global joint analysis with wavelength-dependent radius (i.e., Method 3), Rp/R⋆ is allowed to vary from filter to filter, similar to Method 1. They are listed with Method 1 for direct comparison. The final Rp/R⋆ from Method 3 is a weighted mean of seven filters.
The O–C values are calculated from comparison to T(N) = 2 455 934.792239(40) + N × 0.81347437(13), where N = 0 for this work and N = −256 for Gillon et al. (2012).
The last three columns in this table are calculated from the individual analysis, which are different from those in Table 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.
