Model light curves for 400 randomly selected parameter sets from an MCMC for Model (A). The stars represent the data points and the error bars are 1σ (error bars may be hidden by the markers). Light curves at 3 GHz, 6 GHz, 3.8 × 1014 Hz (F814W), 5.1 × 1014 Hz (F606W), and 1 keV are shown. The decline index α between 260 and 300 days is annotated. The faint point at ∼170 days shows the anomalous F606W point discussed in Section 2.
