Fig. 9


Simulated dynamical PDS containing a QPO at 800 Hz and a smooth frequency jump of 10 Hz initiated at the burst peak (the dashed green line gives the QPO frequency as a function of time). The QPO rms amplitude is 8% and the QPO width is 3 Hz. The LOFT/LAD 3–30 keV light curve of the Type I X-ray burst (peak at 18 times the persistent emission level, rise time of 2 s, and decay time of 7 s) is overplotted with a white line. The persistent count rate was estimated using 4U 1608-522 as the source. The image corresponds to a series of 1 s PDS plotted as a function of time, convolved with a 6 Hz and 2 s averaging kernel. Power is color-coded. We note that the color scale is different from the one used for RXTE data: it saturates at a power level of 8 instead of 3.
