Transit times from all sources for the 37 planets in this work. Target backgrounds are color coded by planetary type: red for hot Jupiters, blue for Neptune-like planets, and green for super-Earths. Points are colored by observatory (gray for ground-based, red for HST, green for TESS, purple for the Spitzer Space Telescope (Spitzer), and blue for JWST) and shaped to distinguish literature data from our own measurements. Our own data comprise the JWST, HST-Ma, HST-Wu, TESS-Wu, and TESS-Wang categories.
