摘要：
We examine the different QPOs seen in X-ray Binaries for an analogous signal to the first AGN QPO. Simple mass scaling rules out the low-frequency and standard high-frequency QPOs. However, the rather unique 67Hz QPO of GRS 1915+105 scales to imply the source is accreting at around Eddington as supported by the SED. The 67Hz QPO is seen when GRS 1915+105 is in a very similar spectral state to that of RE J1034+396 and the power spectrum continuum slopes below the QPOs, are consistent. The difference in normalisation is suggested to be intrinsic and subsequent bandpass corrections yield consistent values.
