Comparison between BAGLE, pyLIMA, and VBMicrolensing’s lensed image centroids for a simulated PSPL event with a parallax. The heliocentric SSB model parameters for this event are t_E,⊙ = 100 days, u_0,⊙ = 1.0, t_0,⊙ = 55775 MJD, π_E,E,⊙ = 0.2, π_E,N,⊙ = 0.1, b_sff  =  1, mag_S = 19, α_L = 269﹩\mathop{.}\limits^{\unicode{x000b0}}﹩3, δ_L = −30﹩\mathop{.}\limits^{\unicode{x000b0}}﹩4, π_S = 0.1 mas, θ_E = 3.0 mas, x_S,0,E,⊙ = −3.0 mas, x_S,0,N,⊙ = 3.0 mas, μ_S,E,⊙ = 1.0 mas yr⁻¹, and μ_S,N,⊙ = 2.0 mas yr⁻¹.
