Left: likeliest values of β depending on the model. “2010 2014” is the nominal orbiting case (Sect. 3.2.1); “2004 2014” is the same model, but taking into account the 2004 observations (Sect. 4.2.1); “Front” and “Back” are the grouped solutions (Sect. 3.2.2); “0.7 M_⊙” is the model with a stellar mass of 0.7 M_⊙ (Sect. 4.2.2); “Static” is the model of a static parent body (Sect. 3.1.1); and “Eccentric” is the model discussed in Sect. 3.1.2. Right: same, but for the dust release position R₀.
