Dynamic SED showing the flux density over wavelength and time (increasing from top to bottom) of the mean-setting and a burst with an energy of 2.3 × 10⁴⁷ erg. Time 0 marks the onset of the burst. Horizontal lines indicate the peak time (white triangles), the time when 80% of the energy is released in the respective band (black dots), and when the flux increase is back at 1.25 times the pre-burst level (gray crosses). The increase in scatter in the (sub)mm range is due to lower synthetic photon counts.
