Microlensing frequency distributions derived from the observed light curves (illustrated with a blue-colored histogram) compared to those obtained from simulated microlensing magnification maps (depicted by gray and black lines). The polygonal lines represent model histograms for various values of R1/2 ranging from 2.0 to 3.0 light-days. The thick line highlights the model’s best fit to the observed data, with R1/2 = 2.2 ± 0.3 light-days. We note that the observational histogram was shifted by −0.07 mag to achieve the best alignment with the model histograms.
