Notes. The first column provides the fitter name. The second column provides methods used by the fitters. The third column provides the number of fitted stars. The fourth column provides the number of parameters used per order. The fifth column provides the number of additional parameters that are common to all the modes and plus those describing the stellar background. The sixth column provides the number of fitted radial orders. The last column provides the range over which the fit is performed. MLE stands for maximum likelihood estimators. MCMC stands for Monte Carlo Markov chain.
