Macro-micro decomposition (MmD) of the C iv (left) and C iii]+Si iii] (right) emission lines obtained from the spectra of images A & D at 4 different epochs. In each panel, the black solid line shows the fraction of the spectrum F_Mμ affected by microlensing and the red solid line shows the emission F_M which is too large to be microlensed. For comparison, we also display the observed spectrum of image D with a dotted blue line and the power-law continuum used to calculate μ(λ,t) with a dashed blue line.
