Trojan hypothesis model after removing the linear baseline model for HAT-P-20. This trojan model is only favored against the null hypothesis if we include the whole data set. However by removing the feature at phases ϕ > 0.20, the null hypothesis is favored. The black shaded vertical line represents the expected egress of the Lagrangian point, showing thelarge time lag of the would-be trojan transit. This light curve corresponds to the data from CAFOS at CAHA on 2017-12-09.
