Left: RV measurements from CHIRON (orange), Fiber-fed Extended Range Optical Spectrograph (FEROS; green), and TRES (purple) for TOI-2494. The RVs are phase folded to the best-fit period for TOI-2494 c, as determined by the EXOFASTv2 global fit. Right: RV measurements from HARPS-N (orange), NEID (green), SOPHIE (blue), and TRES (purple) for TOI-5143, phase folded to the best-fit period of TOI-5143 c, as determined by EXOFASTv2. The best-fit model in each panel is shown in red.
