Corner plots for the G102 white light-curve fit using a linear long-term trend (left-hand panel) and a quadratic long-term trend (right-hand panel). In the case of the quadratic trend, clear correlations between some parameters of the systematics model (⁠|$n^{\rm for}_{\rm w}$|⁠, |$n^{\rm rev}_{\rm w}$|⁠, and |$r_{\rm a2}$|⁠) and the planet-to-star ratio (R|$_{\rm p}$|/R|$_{\rm s}$|⁠) can be seen, as highlighted by the green and red posteriors. Notably, |$r_{\rm a2}$|⁠, the additional parameter which is added to the quadratic fitting has strong correlations with |$n^{\rm for}_{\rm w}$|⁠, |$n^{\rm rev}_{\rm w}$|⁠. In the linear fit, |$n^{\rm for}_{\rm w}$| and |$n^{\rm rev}_{\rm w}$| are not correlated with the transit depth.
