'Eclipses' part of the analysis. The measurements of eclipse timings and depths are translated to orbital and physical parameters of the system using formulae, and the resulting parameters are used as a starting point for fitting an eclipse model of spherical and uniformly bright stars to the data. The eclipse model is supplemented with a sum of sinusoids, obtained by subtracting the initial eclipse model from the data and pre-whitening the residuals. The second to last panel shows the eclipse model in red and the bottom panel shows the supplemental sinusoid model.
