Light curve of the event known as GaiaDR3-ULENS-343, BLG502.29.100629 Mróz et al. (2019), OGLE-2017-BLG-0095, MOA-2017-BLG-160, and KMT-2017-BLG-1123, shown at the top. The GaiaG data is shown in green, G_RP in red, KMTNet data is shown in dark red, violet and aqua for the South African Astronomical Observatory (KMTA), Cerro Tololo Inter-American Observatory (KMTC), and Siding Springs Observatory (KMTS), MOA I and V band data are shown in light green and dark red respectively, and OGLE in light-blue. The four solutions are marked: PSPL without parallax G0 with a black dashed line, and two PSPLs with parallax, G+ and G- with red and grey continuous lines respectively. The bracket in the top left shows the χ² of different solutions. Bottom panel: Residuals of the G+ model. A Black dashed line marks the G0 and G+ models difference, while the dark grey continuous line marks the G+ and G- models difference, respectively.
