The present rate of flux changes from radio to γ-rays for the different models with the observations (Vinyaikin (2007) for radio and Smith (2003) for optical). The thin black line is TT10. The simple continuous acceleration model (see Section 3.1) corresponds to the green dashed line. The thick blue and dotted red lines are the results of Models 1 and 2 in Section 3.2, respectively.
