A plot comparing the periods measured from the ZTF light curves and the TESS light curves. The points are colored by their TESS peak powers. The 1:1 line with 10% uncertainties are indicated with the black line and the shaded region. The 1:2 line is indicated in red. A potential Lomb–Scargle failure mode caused by the window function of the TESS observing sector is indicated as a dashed blue line (more description in text).
