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 FMμ affected by microlensing and the red solid line shows the emission FM 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.
