Caption: Figure 8.

GRS 1915+105: Left: cospectrum before (black) and after (red) clean up of the nth harmonics of the housekeeping operations (at 1 and 0.125 Hz)." Right: evolution of the 1.5 Hz QPO (and a faint first harmonic) in the dynamical cospectrum during the observations. Each time segment represents 64 s of gap-free data. Colors and sizes of the points are both a proxy of power, in arbitrary units.
