Degenerate solutions for MOA-2012-BLG-006. Top center panel d) presents anomaly part of light curves for three modes A, B, and C. All three light curves predict the second subevent at HJD′ = 6047. Remaining large panels a)–c) show the projection of the marginalized χ² hypersurface. Red, orange, yellow, green, and blue points correspond to Δχ² of <1, <4, <9, <16, and <25, respectively. Letters A, B, and C mark the three modes. We note that u_0,1> 0 means that the companion and the host caustics are passed on opposite sides. The data presented on this plot are not the result of a single run, but a compilation of many simulations and were obtained using OGLE data only. Similar plot for OGLE and MOA data does not show significant differences except different levels of Δχ². In particular, MOA data at HJD′ = 5965.2 and 5967.2 significantly contribute to preference of mode A over mode C. The small panels on the right e)–g) show source trajectories of the three solutions relative to planetary caustic (blue curve). Crosses mark the source positions at epochs when OGLE data were taken. Circles have a radius of ρ. In the case of solution B, the source size of ρ = 0.00016 is too small to be seen.
