(a) rms amplitude-flux relation for the ∼4-Hz intermittent oscillations. (b) Frequency-flux relation for the ∼4-Hz intermittent oscillations. The correlation coefficients for non-rebinned points (blue dots) are 0.213 and 0.13, respectively. After binning on mean count rate (red stars), the linear relationships become more clear and their correlation coefficients are 0.51 and 0.41, respectively.
