Using archival spectral data from seven X-ray missions, we have measured the inner accretion-disk radius of the persistent and soft black-hole binary LMC X-3. We fitted the continuum spectra using our fully relativistic accretion disk model. To within a few percent, we find that the inner radius is the same for all missions. These data span more than 25 years and extend over an order of magnitude in luminosity. Given the unrivaled richness of the LMC X-3 data set, our result provides the strongest possible evidence for the existence of a stable inner-disk radius, which is presumably tied to the innermost stable circular orbit (ISCO) that is predicted by general relativity. Our findings establish a firm foundation for the measurement of black hole spin by either of the two methods currently in use, X-ray continuum fitting or Fe-line modeling.
