a) Black-body flux, F_BB in 10^-9   erg   s^-1   cm^-2, and b) photon index, Γ, both strongly correlate with the power-law flux, F_PL. Light-blue triangles and dark-blue squares represent data from the decays of the 2005 and 2007 outbursts, respectively, purple diamonds are from the rise of the 2011 April outburst (Table 1 and Fig. 1).
