Caption: Figure 5.
Top row: the evolution of the semimajor axes a and eccentricities e for HD 33142d (blue), HD 33142b (red), and HD 33142c (green) of a representative stable fit from the posterior distribution. Middle row: the evolution of apsidal angles Δω d−b, Δω d−c, and Δω b−c, which are librating in an antialigned, aligned, and antialigned geometry, respectively. For purposes of providing a clear representation, the plot only shows a 50,000 yr excerpt.
