Top: Kepler light curve (PDCSAP flux) of KIC 9451096 over time, spanning from the 0th quarter through the 17th quarter. The PDCSAP photometry is represented by black dots, showing the brightness variations derived from Kepler observations. Bottom: the PDCSAP light curve derived from the representative Q0 data, after median detrending and compared with the long-cadence light curve at maximum brightness, clearly reveals the O’Connell effect through the asymmetry between the primary and secondary maxima.
