Results of the juliet joint fit to the TESS photometry and ground-based LCOGT and MEarth-South photometry. Top: transit observations of the respective instruments phase-folded to the period of TOI-1075 b. The black curve is the best-fit juliet transit model, and the 68% confidence interval is represented by the gray shaded region. The binned data points with error bars are shown for clarity (white circles). The TESS data are binned in 2 minute intervals, and the LCOGT and MEarth-South data are binned in 5 minute intervals. Bottom: residuals after the data have been subtracted from the best-fit model.
