MmD disentangling of the C IV line profile using the spectra of images A and B of the lensed quasar J0818+0601 secured in December 2017 with the VLT. FM is the part of the spectrum not affected by microlensing. FMμ is the part of the spectrum that is micromagnified. FA = FM + FMμ is the spectrum of image A. These spectra are given in arbitray units. FMμ and FA are shifted upward by two units to enhance visibility. M is the macromagnification factor of image B relative to image A. μ is the microlensing magnification factor. The vertical dotted lines indicate the position of the C IV emission doublet for the systemic redshift z = 2.349. The positions of the intrinsic absorption lines are indicated as in Fig. 1
