Notes.
The maximum likelihood solution, median, mode, and standard-deviation of the posterior distribution for each parameter are shown, as well as the 68.27, 95.45, and 99.73% confidence intervals. Parameters with priors listed are fitting parameters, while the rest are derived. The prior for each parameter can be of the following types:
: uniform,
: normal, or
: truncated normal. Priors without given ranges are improper. The mean longitude λ0 is given at reference epoch: 2 455 500.0 BJD.
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.
