Probability density function (PDF) of the measured S/N p/σp,G (where σp,G is the geometric estimate) as a function of the true S/N p0/σp,0, with no ellipticity and correlation in the covariance matrix Σp. The mean likelihood, 
(full line), tends to 
at low S/N and to the 1:1 relation (dashed line) at high S/N (p0/σp,0> 2).
