Light curves for each waveband. Top: Swift/BAT hard X-rays (14–195 keV). Second: RXTE/HEXTE (20–100 keV). Third: RXTE/ASM (2–12 keV; crosses) and RXTE/PCA (3–20 keV; solid symbols). Fourth: optical and infrared points, from this work (solid symbols) and the literature (other symbols). The horizontal line indicates R-band quiescence (Zurita et al. 2006). Error bars are to within the size of the points. Bottom: radio data from the VLA (solid symbols) and Ryle Telescope (open symbols). Small symbols (after MJD 53410) are 3σ upper limits at 4.7 and 8.4 GHz. The inset plot shows more clearly the deviation from a smooth decay at 4.7 GHz. The dashed vertical line in all plots represents the time of the PCA peak.
