Distribution of the projected Einstein radius R_E/x = R_ED_S/D_L for the microlensing events toward the LMC due to 1 M_⊙ lenses within the standard Galactic halo (blue line). The distribution expected for other lens masses M_L can be obtained by scaling the abscissa by the factor . The purple line shows the cumulative distribution. The most probable value of R_E/x is 28.6 au, the mean is 44.0 au, and the median is 36.5 au.
