Monte Carlo realization of lensed stars for a case with β = 2. For this example, half a million stars with luminosities in the range 50 L_⊙ < L < 5 × 10⁵ L_⊙ are placed in a region with magnification μ_3m > 10. The maximum luminosity corresponds to the observed HD limit for supergiant stars in the local universe Humphreys (1978). The diagonal cut in the red points is just L_obs = 50 × μ L_⊙. The simulation is complete above L_obs ≈ 10⁶ L_⊙. The LF of stars has a slope of β = 2. Blue dots represent stars before magnification and red dots are the magnified stars. In the top-right inset we show the LF of the stars before magnification (blue curve) and the observed LF after magnification (red curve). In the bottom-right inset we show the spatial distribution of the 500 brightest events and for a model with magnification μ = 1″/d where d is the distance to the CC (marked with a vertical light blue line at d = 0″) in arcseconds.
