Top: phased light curve of Gaia DR3 512884726548446848 (TIC 444790258) folded with the primary p-mode period P₁ = 0.111028 day and epoch T₀ = HJD 2461253.3869, displayed over two phase cycles (0.0–2.0). Ground-based Sloan g observations from the Explorer Observatory (MPC M19) are shown for three consecutive nights: HJD 2461253 (blue circles), 2461254 (green circles), and 2461255 (red circles). Gray points represent TESS QLP space photometry shifted by +1.454 mag to match the Sloan g baseline (Sectors 18, 24, 25, 52, and 58). Bottom: periodogram showing the main period corresponding to the DSCT pulsation.
