Evolution of the ratio of the unabsorbed flux of the incident Comptonization spectra and that of the relativistic and distant reflection components vs. time. The fluxes of relxillCp, which models the relativistic reflector, and those of xillverCp, which models the distant reflector, were corrected by the multiplicative model nthratio (see Sect. 3.2.2). ℱ_relxillCp/ℱ_Nthcomp indicates the geometrical information of the accreting system.
