Comparison of dominant and secondary frequencies between Gaia and TESS. Left: comparison of the measured dominant TESS frequency against the Gaia frequency for the g-mode pulsators (top) and p-mode pulsators (bottom), coloured by the amplitude of the variability (ppt). Right: same but for the secondary frequency. The dashed lines indicate the half, unity, and twice relationships among the frequencies. We compare the sample of g-mode candidate pulsators before removing combination frequencies, to match the method of Aerts et al. (2023). The crisscross structures in the p-mode plots are caused by aliases of the true signal around the Nyquist limit.
