Example of AFINO models applied to a stellar flare detected in TIC 33878971 (top panel) and TIC 303443210 (bottom panel). From left to right: (1) Flare light curve showing the observed flare variations, highlighting the detected QPP peaks. (2) Single power-law model fit to the power spectrum (solid line), highlighting no QPP detection. (3) Power-law model with a Gaussian bump (solid line), demonstrating excess power at a specific frequency indicative of quasi-periodic pulsations. The vertical dashed red line denotes the f_p, the location of the bump in the PSD. The dashed orange line indicates the ± 2σ confidence interval around the fitted power-law component. (4) Broken power-law model fit.
