Cycle–Cycle Mod 2 diagram of V496 UMa for all high-cadence TESS data. Two consecutive cycles are drawn consecutively from the beginning. The color bar shows the flux density. The left panel shows data obtained in sector 15; the right panel shows data obtained in sector 16. All data were folded using the ephemeris given in Eq. (1). The wide white gaps in the two graphs show where TESS did not receive data.
