Macro-micro decomposition (MmD) around the main emission lines. In each panel, we show the part of the line profile which is only macrolensed, F_M, and the part of the line profile which is both macro- and micro-lensed, F_Mμ. The spectrum of Image #2 (F₂ = F_M + F_Mμ) is superimposed (dotted line). The vertical dotted line denotes the rest wavelength of the emission line (using z_s from Table 1). The values of M and μ are given for each decomposition (Sect. 4.1). F_Mμ contains the micro-magnified continuum and, quite often, a part of the emission line profiles, while F_M contains the bulk of the emission lines unaffected by microlensing.
