Top: Probability of Δmag ≤ −0.32 versus Einstein radius crossing time (t_E [years]), with blue (orange) representing values obtained for a stellar density of 0.1 (0.2) and a 1.0 × {r_s}, the red stars represent the object that shows the smaller Einstein radius crossing time and high magnification probability that correspond to DESJ2038-4008 and Q2237+030. Bottom: Probability or Δmag ≤ −0.32 versus source crossing time (t_S [years]), with blue (orange) representing values obtained for a stellar density of 0.1 (0.2) and a R_S× 1, in black stars the objects that show the smallest source crossing time and hight probability that are CY2201-3201, WG2100-4452, SDSSJ1138+0314, SDSSJ0821+4542, J0343-2828, WG0214-2105, and Q2237+030.
