Example for the analysis of the synthetic single-dish light curves. Top panel: the single-dish multi-frequency light curves (2.6 to 345 GHz) computed for b = 1.5, s = 2.5, k = 3.0, ρ = 1.0, and d = 0 (see also Fig. 1). Bottom panels, from left to right: flare amplitudes, flare time scales and cross-band delays. The solid lines correspond to power law fits and the exponent is given in the plots.
