M–D_L region for all the models. The blue stripe with the dashed line represents the M–D_L relation obtained by microlensing parallax (π_E). The red stripe with the dot-dashed line shows the constraint from the lens flux, for which the MLRs for low-mass stars are used. The green stripe with the continuous line exhibits the constraint obtained from the finite-source effects (Boyajian et al. 2014) and the angular radius of the source. All the stripes have a range of 1σ.
