Frequency marginal distributions of the parameters of the two-spot model with DR for ϵ Eridani. From top to bottom: area of the first (solid line) and the second (dashed line) spot; colatitude of the first (solid line) and the second (dashed line) spot; deviation of the longitude of the first spot (solid line) and of the second spot (dashed line) from their initial longitudes, respectively; rotation period of the first spot (solid line) and of the second spot (dashed line); reference flux; inclination of the stellar spin axis.
