Temporal evolution of the SED. The color encodes the time: dark red to dark blue as indicated in the color bar. For two time steps, the X-ray spectrum can be split up into two points (T2 and T3). For T4, only one X-ray flux measurement is possible. The upper limits are plotted for T1, T5, and T6. The measurements in the NIR are indicated by thick lines, with the uncertainties indicated and extrapolated by the shaded area. The submillimeter data shown are the same as in Fig. 4.
