Error values indicate the 95% confidence intervals estimated from MCMC resampling.

ND, not determinable.

Values were held constant throughout the fitting procedure.

Values were not directly fit, but calculated from the fitted parameters and associated 95% confidence intervals calculated from MCMC chains of the dependent fitted parameters.
