3 Lightcurves

Lightcurves for all objects were constructed by dividing the line-free region of the continuum between $\sim$5300-5700 Å by the average of that region. The Fourier transforms of the light curves were calculated up to the Nyquist frequency and are shown in Fig. 1. No clear periodicities are evident for G 67-23, G 1-7, and G 126-18, as expected based on the limits of $0.25\%$, $0.37\%$, and $0.46\%$ respectively set by Kepler et al. (1995).
