Distribution of AL-projected residuals from Gaia FPR per observation (i.e. not averaged by transit). For each panel, we select an interval of per-observation random errors projected in AL (γ) from Gaia FPR. For all observations in the Gaia FPR catalogue with γ within this interval, we retrieve the corresponding residuals; their distribution is shown in pink, with the empirical mean and std $\hat{\gamma }$ indicated. The distributions in the top, middle, and bottom plots contain 22k, 45k and 56k observations, respectively.
