DHO fits for realistically simulated SDSS S82 light curves; the input model parameters are drawn from the distribution shown in the top two panels of Figure 3. The DHO fits that are identified as good using the algorithm described at the beginning of Section 4.1 are color-coded by the difference between their best-fit log(ω ₀) and the input. Identified bad fits that were simulated as overdamped DHOs are shown using gray dots and those simulated as underdamped DHOs are shown using magenta crosses. The orange dashed line marks a T _QPO of 1 day. The cyan dashed–dotted line shows the cut used to remove the bad fits associated with the daily observing cadence (surrounding the orange dashed line). The red contour outlines the distribution of the input DHO parameters.
