Comparison of noise statistics between different light curve sources and observing cadences, including all stars with 20-s cadence observations where a custom aperture was constructed (cf. Sect. 3). Top left: RMSD of 20-s light curve flux binned to 1 hour against TESS magnitude for both SPOC and custom aperture data. Top right: P2P-MDV of 20-s light curve flux binned to 120-s against TESS magnitude. Bottom left: ratio between the 1-hour RMSD from 20-s and 120-s cadence custom aperture data. The red markers indicate median-binned values, with uncertainties given by the standardised MAD, while the green markers give the ratios provided by Huber et al. (2022) (their Table 1). Bottom right: ratio between P2P-MDV from 20-s (binned to 120-s) and 120-s cadence custom aperture data. Red markers again indicate median-binned values, with uncertainties given by the standardised MAD.
