FINKER’s frequency search for ZTF J041016.82–083419.5. The panel on the left shows the frequency range searched, and the inset illustrates the behaviour of the residuals around the minimum. Transit data shows a less smooth behaviour of the residuals around the minimum, but the frequency and its uncertainty, shown as a black error bar, are consistent with the literature value. The panel on the right shows the light curve folded at the found frequency with the kernel regression fit (green line) overlaid.
