Notes. G0 is the point source–point lens model without including a microlensing parallax effect. GL (Gaia-long), GS+ (Gaia-short-positive u0) and GS− (Gaia-short-negative u0) are the point source–point lens models including a microlensing parallax effect. For G0, we chose the model with u0 > 0, because the posterior distribution for u0 was symmetrical.
