L.A.S. and T.M.E. were partially supported during this work by the NASA Citizen Science Seed Funding Program via grant No. 80NSSC22K1130 and the NASA Exoplanets Research Program via grant 80NSSC24K0165. Those NASA grants also support the UNITE (Unistellar Network Investigating TESS Exoplanets) program, under the auspices of which the Unistellar data were collected. P.A.D. acknowledges support by a 51 Pegasi b Postdoctoral Fellowship from the Heising-Simons Foundation. D.D. acknowledges support from the NASA Exoplanet Research Program grant 18-2XRP18_2-0136. This study also benefited from the kind contributions of the Gordon and Betty Moore Foundation.

The scientific data highlighted in this paper were partially sourced from the Unistellar Network, a collaborative effort between Unistellar and the SETI Institute. We extend our gratitude to Frédéric Gastaldo for financially supporting the foundational phase of the Unistellar Citizen Science project. We express our heartfelt appreciation to the citizen astronomers who shared their invaluable data for these observations. This publication also makes use of data products from Exoplanet Watch, a citizen science project managed by NASA's Jet Propulsion Laboratory on behalf of NASA's Universe of Learning. This work is supported by NASA under award number NNX16AC65A to the Space Telescope Science Institute, in partnership with Caltech/IPAC, Center for Astrophysics∣Harvard & Smithsonian, and NASA Jet Propulsion Laboratory. Part of this research was carried out at the Jet Propulsion Laboratory, California Institute of Technology, under a contract with the National Aeronautics and Space Administration (80NM0018D0004).

We thank Ken and Gloria Levy, who supported the construction of the Levy Spectrograph on the Automated Planet Finder. We thank the University of California and Google for supporting Lick Observatory and the UCO staff for their dedicated work scheduling and operating the telescopes of Lick Observatory. Some of the data presented herein were obtained at the W. M. Keck Observatory, which was made possible by the generous financial support of the W. M. Keck Foundation and is operated as a scientific partnership among the California Institute of Technology, the University of California, and NASA. The authors wish to recognize and acknowledge the very significant cultural role and reverence that the summit of Mauna Kea has always had within the indigenous Hawaiian community. We are most fortunate to have the opportunity to conduct observations from this mountain.

This paper includes data collected by the TESS mission. Funding for the TESS mission is provided by the NASA's Science Mission Directorate. This research also made use of the NEA, which is made available by the NASA Exoplanet Science Institute at IPAC, operated by the California Institute of Technology under contract with the National Aeronautics and Space Administration. Additionally, this research made use of the Exoplanet Follow-up Observation Program (ExoFOP; NExScI 2022) website, which is operated by the California Institute of Technology, under contract with the National Aeronautics and Space Administration under the Exoplanet Exploration Program.
