τ for the N (pH 6.1), MG (pH 4.1), and U state (pH 2.2) for the different mutants. The FFHS model was used to estimate τ from ρ. The standard deviation of independent measurements of ρ was used to estimate the error bars. Note that the inset has a different vertical scale. Lines are to help guide the eye.
