TTVs for the six claimed exomoon candidate hosts of Fox & Wiegert (2020), with our own measurements in black and those of Holczer et al. (2016) in brown. We overplot the best-fitting sinusoid with the χ² improvement shown in the lower left corner (and similarly for that of Holczer et al. 2016 in the lower right, although we do not plot the associated sinusoid).

(The data used to create this figure are available.)
