摘要：We examine the evolution of the color radius and GRS 1915+105 and compare that to predictions made by the Magnetic Flood Model. This model applies a linear correction to associate the Low Frequency QPO to the Keplerian frequency. Because spectral fits to the X-ray data using XSpec often produce erroneously low color radius results, the quantity is often ignored, but the trend is assumed to be a valid trace of the inner disk radius. We show that, if the radius trend established by the X-ray spectral fits can be believed, then no monotonic solution can rectify the QPO frequency to the Keplerian radius. We discuss various caveats and analases that may be performed to further test the Magnetic Flood model.
