Multi-component decomposition of carbon line profiles and microlensing of emission lines. The top and middle panels display decompositions into four (C iii] narrow + C iii] broad + Si iii] + Al iii) and three (C iv narrow + C iv broad + He ii complex) Gaussians, respectively. The bottom panel incorporates the microlensing magnification ratios of the line cores: decomposition of carbon lines (filled black circles; see Sect. 3.2), standard stratification of the BLER (green circles; see Sect. 3.1) and non-standard stratification of the BLER (red circles; see Sect. 3.1). This last panel also shows the microlensing of the C iii] and C iv broad emission lines (open black circles).
