Errors are standard deviations obtained from the diagonal elements of the covariance matrix calculated from the likelihood function (maximum likelihood method) or chi-square function (donor-acceptor cross-correlation calculation).
ln L = ln L (4-state) - ln L (2-state).
Baysian inference criterion (BIC) was calculated by BIC = -2ln L + nln Np, where n is the number of parameters and Np is the number of photons. BIC = BIC (4-state) - BIC (2-state).
