![]() ![]() ![]() In a large fraction of the sky we recover 30% to 50% of warm Jupiter systems (planet radius of 0.9 to 1.1 R J subscript □ □ R_ italic_R start_POSTSUBSCRIPT italic_J end_POSTSUBSCRIPT and 13.5 < P < 50 13.5 □ 50 13.5 < italic_P < 50 days). We find that KELT photometry can be used to confirm ephemerides with high accuracy for planets of Saturn size or larger with orbital periods as long as a year, and therefore span a wide range of planet equilibrium temperatures. We insert simulated TESS-detected single transits into KELT light curves, and evaluate how well their orbital periods can be recovered. We explore the use of existing ground-based wide-field photometric surveys to constrain the ephemerides of the TESS single-transit candidates, with a focus on the Kilodegree Extremely Little Telescope (KELT) survey. Follow-up observations of transits of these candidates will require precise ephemerides. For planets with orbital periods longer than 13.5 days, TESS can only capture one or two transits, and the planet ephemerides will be difficult to determine from TESS data alone.
