Notes. Times t0 and t are in [MJD]; fluxes are in units of [10-5 ph cm-2 s-1] ; the significance of the flux difference is in [σ] ; the absolute values of the observed characteristic time scale |τ| and the intrinsic one |τint| = |τ|/(1 + z) are in hours. The last column indicates a rise (R) or a decay (D) time.
