Probability of finding the true polarization fraction p0 inside the interval , where and are the lower and upper limits of each estimator: credible intervals ML/MAP (blue), a posteriori variance MB (pink), and MAS variance (orange). It is plotted as a function of the S/N p0/σp,G. 10 000 Monte-Carlo simulations for each setup of the S/N have been performed assuming a covariance matrix in the low regime. The Gaussian level at 68% is shown as a dashed line.
