Deviation, σ_s,e, of transit borders’ timing, versus β estimates, confirming the negative derivative ∂σ_s,e∕∂β in Eq. (7) for the ingress (panel a) and egress (panel b) parts of the TLC. Only objects with r_se < 0, β > 0.07, and border timing errors ε_s,e < 0.0007 days from Table A.1 were included. The solid lines show the corresponding regressions. Panels c and d are the same as panels a and b, but for the confirmed planets with status “p” only, irrespective of extensions (“!”, “*”, “?”).
