Notes. * The observations are ordered according to the 2−10 keV intensity (rising – peak – declining), or equivalently, according to the hardness ratio (decreasing – minimum – increasing). † The position is relative to the flare on MJD 60206. ‡ Type-C QPO is not detected and we give 95% confidence upper limit of the fractional rms, ≤1.8% in the LE 2 − 10 keV band and ≤1.5% in the HE 28 − 200 keV band.
