Raw light curves for the four visits of GJ 3929 b. The light curves shown use aperture photometry with an aperture radius of 5 pixels and a background annulus spanning 12–20 pixels. The extent of the detector-settling ramps for each observation are marked with red dashed lines (500 integrations). The gray shaded region shows the expected eclipse time for a circular orbit. Visit 4 consists of two observations, with a discontinuity shortly before the expected eclipse ingress. We see a possible tilt event in visit 4 around 3.5 hr before 0.5 phase.
