Parameter distributions considering the X-ray LC part of the SED. Blue lines: steep-decay phase. Red lines: plateau. Gray lines: normal decay phase. a)β_op,X: the spectral slopes calculated using a power-law as fitting function. b)β_X and c)β_op: the broken power law spectral slopes for the X-ray and optical data, respectively. d) N_H,PL and e)N_H,BR: the hydrogen column densities obtained using as SED fitting function a single power-law and a broken power-law, respectively. f)ν_rest,BR : the rest frame break frequency calculated fitting the SEDs with a broken-power law.
