Long-term TTV candidates from the full dataset. Comparison of the quadratic model against the linear model for targets with more than five transit times. The red dashed line marks ΔBIC = 10. The color bar encodes the period-derivative significance ﹩\dot{P}/{\sigma }_{\dot{P}}﹩. Targets satisfying ΔBIC > 10 and ﹩\dot{P}/{\sigma }_{\dot{P}}\gt 3﹩ are annotated.
