Using a self-consistent Comptonization model, we show that one can analyze spectra that exhibit strong power-law components and obtain values of the inner disk radius, and hence spin, that are consistent with those obtained in the thermal dominant state. Specifically, we analyze many RXTE spectra of two black hole transients, H1743-322 and XTE J1550-564, and we demonstrate that the radius of the inne","authors_text":"James F. Steiner, Jeffrey E.
