The passage around this formula

Lay all of it out in one table, rows for experiments and columns for the five components, and four columns get real entries: ηcl\eta_{cl} constrained at the 10^{-15} level by MICROSCOPE, η^diag\hat\eta_{diag} constrained by every dual-species and clock test in the list, η^coh\hat\eta_{coh} constrained at the low- 10^{-9} level by Rosi and colleagues’ internal-superposition test, η^sup\hat\eta_{sup} constrained by Overstreet and colleagues’ gravitational Aharonov-Bohm result. The fifth column,…
