Light curves produced for each pixel in Figure 6 phase-folded on a period of 2.1 days, the period of the classical Cepheid Gaia DR3 5340164256296564736. The light curve for the pixel hosting the Cepheid is highlighted with a red frame. The 2.1 days signal is dominant in the light curve extracted from that pixel, as expected, but also in those extracted from many surrounding pixels. The y-axes of these plots share a flux scale, demonstrating the relative strength of the 2.1 days signal.
