Comparison of the microlensing light curves. The optical r-band light curves are shown for the photometric data (gray) and the spectroscopic data (black). The continuum adjacent to the emission line is displayed in green color, and the BEL wings of C IV (top) and C III] (bottom) in blue and red colors, respectively. We want to emphasize the remarkable consistency between the microlensing light curves obtained from spectroscopic data for the r-band emitting region and the results obtained from photometric monitoring data. We note that all observations are presented in the time frame of the leading image C.
