Successive construction of models for u0 > 0, analogous to the u0 < 0 case presented in Table 3. Step 1 is identical to the procedure for u0 < 0 (given that it the single-lens point-source light curve without parallax depends on |u0| only), whereas for the other steps the opposite sign for u0 has been enforced, leading to a flip in sign of the trajectory angle α (or respectively α↔α ± π), while all other parameters differ slightly.
