Comparison of a simulated PSPL event without a parallax between VBMicrolensing, pyLIMA, MuLensModel, and BAGLE. The amplification (top) and residuals with respect to the BAGLE model (bottom) are shown over time. The differences in the lightcurves are at machine precision. The heliocentric SSB model parameters for this event are t0,⊙ = 55775 MJD, u0,⊙ = 1, tE,⊙ = 100 days, bsff = 1, and magS = 19.
